A wide variety of geotechnical problems can be solved using Finite Element techniques.
These include soil, seepage, soil-structure-interaction, settlement, and displacement
Analysis of gravity/flexible retaining walls, piles, and tunnelling problems can be carried out
using 2D and 3D elements. Material models available include Cam-Clay, Drucker-Prager,
Elastic, and Nonlinear Geological materials.
Analysis of Sheet Pile Walls
The following example shows a sheet pile abutment for an integral bridge in which the
displacements and rotations of the piles are predicted. As shown in the following view a 3D
model is used with the soil modelled as 4 layers of elastic material.
The following picture shows an exaggerated view of displacements together with the sheet
pile effective stresses, under a laterally applied load to the pile cap.
Soil Consolidation Analysis
An example of the type of soil consolidation analysis that can be carried out is shown in the
ADINA Newsgroup. The distribution of excess pore pressure and the displacement under
the applied load is computed for a simple three-layered soil model.
