Summary
This tutorial identifies the soil–structure interaction by analyzing construction stage of 3D retaining wall excavation and a piled foundation. It is possible to review in detail the stress distributions on cross-sections, which is not possible in 2D models. Also, interface is added between ground and retaining wall to simulate the ground-structure interaction more
realistically. The evaluation of the soil-structure behavior is done by using pile elements, not by simple beam elements. Also, pile elements are perfect for evaluating the soil-structure behavior because it can consider the influence of interface between pile and adjacent ground.
