Product Overview:

This video provides a step-by-step simulation of a Tunnel Boring Machine (TBM) operation in dry and saturated soil conditions using Abaqus. The soil is modeled as a three-dimensional part, divided into two zones to represent dry and saturated areas, and utilizes Mohr-Coulomb plasticity for material behavior. The tunnel liner is modeled as a three-dimensional shell with concrete properties.

The simulation involves several phases: the first step applies the soil’s body force, the second step focuses on excavation, the third step addresses soil relaxation, and the final step incorporates the tunnel lining. The transient soil step is used as the most suitable approach for this type of analysis.

Key Topics:

• Part creation for soil and bulwark components with realistic dimensions.
• Setting up material properties such as density, Young’s modulus, and Mohr-Coulomb plasticity.
• Applying geostatic loading conditions and boundary conditions to simulate real-world scenarios.
