The research application about large deformation FEM in the pile-soil interaction mechanism of jack-up platform

The most commonly used in modeling of soil deformation and bearing capacity is the MohrCoulomb model, which is applicable to both drained and undrained soil strengths. The soil structure and the associated properties used in the model were based on documents (Yi et al., 2012). The mesh models of ALE and CEL as shown in Figure 1 and Figure 2. It should be marked off districts, so the pile is convenient to penetrate into the soil and also it increases the efficiency of the FEM. The rigid pile (Hossain et al., 2005) model is shown in Figure 3.
