Construction projects often involve earthwork, foundations, roads and tunnels. Designs of foundations and excavations require accurate analyses of soils and soil-structure interactions. Deformations in soils are affected by the flow of pore fluid in the soil and the implications of this coupled phenomenon need to be taken into account for design purposes. The interactions between the soil and the adjoining non-soil structures are also important aspects of the overall construction design.
SIMULIA provides realistic simulation solutions that allow accurate predictions of soil deformations and soil-structure interactions. Time-dependent deformations including consolidation of the soil can be predicted accurately as the solution is based on a fully coupled system involving stress and pore fluid diffusion. Additionally, the contact between the soil and the adjoining structure satisfies fluid continuity and stress equilibrium simultaneously, resulting in rational predictions. Fully coupled transient or fully coupled steady-state analyses can be performed using a wide range of geotechnical material models and loading/boundary conditions, and the construction and excavation processes can be modeled through element addition and removal.
