Finite Element Analysis with Joint Element for Model Pile under Vertical Loading

Wu, Yang / Yamamoto, Haruyuki

This paper presents the finite element analysis of the model pile loading test considering large deformation theory. The area around pile tip is concentrated with significant compressive and shear stresses. A constitutive model with particle crushing is adopted to describe the mechanical behavior of model ground. The jointed element is introduced in numerical analysis to simulate the interaction between pile and its surrounding soil. The predictions of the relationship between the normalized bearing stress and displacement are good agreeable with the test results. The influences of the joint element on the accuracy of the predicted values are obtained. The figures of distribution for displacement vectors with different penetration depth are shown and discussed.
