How to Simulate a Deep Excavation

Learn how to simulate a deep excavation using COMSOL Multiphysics and the Geomechanics Module. Step-by-step instructions demonstrate the modeling process of a 26-meter deep excavation. The excavation steps in the soil are simulated using a parametric sweep, while the soil plasticity is studied with a Drucker-Prager criterion. The soil-retaining wall interactions are computed using the Solid Mechanics interface. Results shown consist of two 2D plots (deformation of the soil and retaining wall, and the plasti
