Introduction to Soil Analysis and Simulation

Soil analysis and simulation are fundamental processes in understanding, managing, and predicting soil behavior for agriculture, civil engineering, and environmental applications.

Soil Analysis involves the study of the physical, chemical, and biological properties of soil. The goal is to assess its fertility, structure, and suitability for different uses. Typical parameters include:

  • Physical properties: texture, structure, density, porosity, and moisture retention.
  • Chemical properties: pH, nutrient content (nitrogen, phosphorus, potassium, etc.), cation exchange capacity, and salinity.
  • Biological properties: microbial activity and organic matter content.

By analyzing these characteristics, scientists and engineers can determine soil quality, diagnose deficiencies, and make informed decisions for crop management, land use, or construction projects.

Soil Simulation is the use of computational models to predict how soil systems respond to natural and human influences. These models can simulate:

  • Water flow and retention in soils (hydrological models).
  • Nutrient cycling and plant uptake.
  • Soil erosion and sediment transport.
  • Soil–structure interactions in engineering.

Simulation tools help forecast the long-term impacts of climate change, irrigation practices, fertilizers, and land management strategies on soil health. They are also essential in designing infrastructure that interacts with soil, such as foundations, pavements, and embankments.

Importance

  • In agriculture, soil analysis and simulation optimize crop yields while reducing environmental impacts.
  • In civil engineering, they ensure safe and sustainable construction practices.
  • In environmental science, they help model pollutant transport, carbon sequestration, and ecosystem health.

Course Content

Example 1: Embankment construction with geocell on the saturated soil
In this lesson, the embankment construction with geocell on saturated soil in Abaqus is studied. The soil is modeled as a two-dimensional shell part, and it was separated into zones as dry and saturated. The embankment is modeled as a two-dimensional shell part, and it was separated into three zones. The geocell layers are modeled as a two-dimensional wire part. To model soil behavior, an elastic-plastic material with permeability to consider pore pressure value during the analysis is used. The elastic material is selected for the geocell parts. In the first step, the Geostatic step is considered to obtain equilibrium in all parts. In the second step, the soil step is selected, and during that, the first layer of geocell is added to the model. Totally seven steps are defined to apply all the layers of the embankment and geocell to the model. At the end, the soil step with a long time period is used to make consolidation in the model. All interactions are assigned to the three layers of the embankment and geocells. The fixed boundary condition is assigned to the bottom side of the soil, and also zero pore pressure to the dry zone. The body force load is applied to all parts, and also the initial stress because of the elevation is assigned to the soil.

Example 2: Creating a geocell Reinforced Foundation for Soil
In this section, the Simulation of the Pressure Distribution on Subgrade Soil Underlying Geocell geocell-reinforced foundation Bed in Abaqus is studied. High contact stresses generated in the foundation soil, owing to increased load, cause distress, instability, and large settlements. Present day, geocell reinforcement is being widely used for the performance improvement of foundation beds. With an increase in loading due to high-rise structures, contact pressures on foundation soils have increased manifold, leading to distress, instability, and large settlements. Hence, the requirement for the improvement of soil has increased markedly. The introduction of geosynthetic reinforcements in the foundation soil is a potential solution. In this avenue, geocell reinforcement is a recently developed technique that offers overall confinement to the soil within its three-dimensional pockets, thereby increasing the overall rigidity of the soil bed, leading to improved performance. Commercially available geocells are manufactured from high-density polyethylene sheets, ultrasonically welded in a honeycomb pattern. The soil is modeled as a three-dimensional solid part, and the geocell is modeled as a three-dimensional shell part. To model geocell behavior, elastic data, and to model soil behavior, elastic data with Cap model plasticity with hardening are used. The two static steps to apply uniform pressure from the soil above the foundation and apply the normal load on the footing zone are considered. The geocell part is embedded inside the concrete host, and a fixed boundary condition is assigned to the bottom surface of the soil. The gravity is applied to all parts in the first step, and uniform pressure is applied to the top surface of the soil part. The load as a velocity type is selected to apply the load on the footing zone in the middle of the soil.

Example 3: Modeling a concrete Vessel contains water Embedded in Soil under seismic laod
In this case, the analysis of the water sloshing in the buried concrete tanks in soil subjected to seismic loading is investigated. To model soil behavior, Mohr-Coulomb plasticity and elasticity are used. For the water Us-Up equation of state and for the concrete CDP model are used. The dynamic explicit step is used to investigate water sloshing during an earthquake. The surface-to-surface contact between water and tank, without a zero value for the friction coefficient, is used. The contact between soil and concrete is assumed as a surface-to-surface contact with a contact property. The fixed boundary is assigned to the bottom surface of the soil part, and in step one, acceleration is applied to the soil. The geostatic stress, as the predefined field, is assigned to the soil. Earthquake brings huge losses in the development of human society repeatedly, which is one of the most serious natural disasters facing humanity. The world’s earthquake occurs about 500 million times every year, of which magnitudes 6 and above are about 100 to 200 times, and magnitudes 7 and above are about 18 times. Earthquake loads have usually been considered in their design, but the analyses have been based on a simplified theory developed for retaining walls with the wall top at the ground surface and the foundation assumed to be rigid. When the structure is constructed below the surface in deep soil layers, these simplified methods have obvious limitations. The tank, soil, and water are modeled as a three-dimensional solid part.

Example 4: Analysis of the Geotextile Reinforced Soil Retaining Wall
In this lesson, the analysis of the Geotextile Reinforced Soil Retaining Wall in Abaqus is done through a practical model. The soil is modeled as a two-dimensional part with elastic, cap plasticity material with hardening. The geosynthetic is modeled as a two-dimensional wire model with elastic material and with a beam element. Sequential Construction of a Geotextile-Reinforced Soil Retaining Wall using FEM. Using the sequential construction procedure (layer by layer), analyze the 3-m-high geotextile-reinforced soil retaining wall. For this simulation, ten general static steps for sequential construction have been used. In each step, one layer of soil and geosynthetic is added to the model, and gravity load is applied to that layer. The geosynthetic is used as an embedded region in soil.

Example 5: Modeling the interaction between soil and a pile raft
In this section, the analysis of the concrete piled raft in interaction with soil in Abaqus is demonstrated. The piled raft foundation system has recently been widely used for many structures, especially high-rise buildings. In this foundation, the piles play an important role in settlement and differential settlement reduction, and thus can lead to economical design without compromising the safety of the structure. In several design cases, the piles are allowed to yield under the design load. Although the load capacity of the pile is exceeded, the piled raft foundation can hold additional loads with controllable settlement. Thus, accurately determining the settlement of the foundation is critical, and for this, the designers must consider the role of the raft and the role of piles in combination, as well as the interactions between the foundation’s components.

Example 6: Analysis of the Earthquake of a concrete tunnel in the soil
In this case, the analysis of the Earthquake of a concrete tunnel in the soil is investigated. The tunnel industry has considered that tunnels, especially tunnels in rock, are naturally resistant to earthquake action, including faulting, shaking, deflection, and ground failure. As the number of case histories of tunnels subject to earthquake action has increased, the industry has started to recognize that, although tunnels in rock have good resistance against earthquakes generating peak ground accelerations (PGA) lower than 0.5 g, it is important to include the dynamic forces and displacements generated by seismic ground motions in the design process to obtain a more reliable design. The soil and concrete tunnel are modeled as two two-dimensional parts. CDP(concrete damage plasticity) for concrete and Mohr-Coulomb plasticity for soil have been used. This simulation has been done in three stages. In the first stage the the soil weight is assigned to the soil part. In the second step, the gravity is assigned to all parts, and in the third step, the earthquake acceleration is applied to the assembled part. Geo stress is the other parameter which assigned to the soil by using a predefined field.

Example 7: Simulation of the embankment and excavation on saturated soil
In this lesson, the simulation of the embankment and excavation on saturated soil is done through a practical tutorial. A two-dimensional space to model the ground and embankment as a shell part is used. Because of humidity, in the property modulus, permeability constant, elasticity, and Coulomb plasticity have been implemented. GEostatic step is used to model the equilibrium between soil elements. After that, three soil steps are used to model the three stages of embankment construction, and after that soil transient step is applied as the first consolidation step, is applied. After consolidation, again three processes, as the excavation step and the soil transient step, and the consolidation step. Body force is applied to all parts in the proper step for each member, and GEOSTRESS for dry and saturated soil is considered separately as elevation from the center of the coordinate.

Example 8: Modeling of Consolidation in Clay Soil
In this case, the analysis of the soil consolidation in interaction with a concrete pile is investigated. All parts have been modeled in one part, and a three-model was created with partition as soil zone, pile, and cohesive for modeling the interaction between pile and soil interference. Analysis contains three steps. In the first step, soil body force is applied; in the second step, pile load is applied. In the third step to model the consolidation phenomenon, soil steps with a long time have been selected

Example 9: Modeling Geosynthetic-Reinforced Soil
In this lesson, the analysis of the geosynthetic-reinforced soil retaining wall, besides the heap soil, is considered. Using backfill soils with cohesive fine contents to build geosynthetic-reinforced soil (GRS) retaining walls for permanent purposes has attracted considerable attention in recent years. Such back fills are considered to be marginal since they contain cohesive fines that have a plasticity index (PI)>6, and major may not exceed 15%. If justified, this practice can increase the cost-effectiveness of GRS walls. However, unlike clean granular soils, soils with cohesive fine contents generally exhibit distinctive creep response under constant loading, and GRS walls with such back fills have time-dependent responses that are very different from those using clean granular back fills. In this video Simulation geosynthetic-reinforced soil retaining wall beside a heap of soil in Abaqus has been done. To simulate the geosynthetic part Beam element has been used.

Example 10: Modeling a Construction Embankment on Soil
In this section, the analysis of the embankment construction on a saturated soil floor is done. An elastic material with Coulomb-Mohr plasticity for soil has been used. Because of the saturated soil permeability, in material property is definite. In this analysis, seven steps are involved: in step one, soil body force, in step two to seven embankment construction; and in step seven, rest for all parts as the soil step with a long time has been applied. During the construction, stress increased in the soil, and after that, pore pressure decreased because the soil dried from saturation and lost humidity.

Example 11: TBM modeling in the dry and saturated soil
In this model, the simulation of the TBM modeling in the dry and saturated soil in Abaqus is investigated. The soil is modeled as a three-dimensional part with two separate zones to assign dry and saturated conditions with Mohr-Coulomb plasticity. Liner is modeled as three three-dimensional shells with concrete material. This analysis contains some steps: in the first step, soil body force, in the second step, excavation, in the third step, relaxation, and in the fourth step, lining has been applied.

Example 12: Analysis of the pile in interaction with soil under vertical load
In this section, the analysis of the pile penetration in the soil using the infinite element method is studied through a comprehensive tutorial. To model this tutorial, the two-dimensional model has been used . Concrete pile is modeled as an elastic material and Mohr-Coulomb plasticity with variant elastic properties depending on elevation for soil has been implemented. An infinite element for modeling an area far from the load zone in the soil by changing the input file and modifying it has been applied. To simulate this tutorial, four steps were used.

Example 13: Pile jackinginto the Soil using the Eulerian approach
In this case, the pile jacking into the Soil using the Eulerian approach analysis is done. Soil has been modeled as an Eulerian part with Coulomb-Mohr material. Pile has been modeled as a 3-dimensional Lagrangian part of concrete material. An explicit procedure is appropriate for this analysis, and two steps have been defined: in the first step, soil body force was applied, and in the second step pile penetrated the soil.

Example 14: Analysis of the earthquake load over a gravity dam in interaction with water and soil by using infinite element method
In this lesson, the analysis of the earthquake load over a gravity dam in interaction with water and soil by using the infinite element method is investigated through a practical tutorial. All parts are modeled as two-dimensional, and for dam CDP material, for soil Mohr-Coulomb, and for water Acoustic property as Bulk Modulus, has been used. An infinite element for soil far from the foundation was created. A dynamic implicit step is appropriate for this type of analysis, and the time of this simulation was 10 seconds, and the acceleration that comes from the earthquake was applied to the depth of the soil.
