Analysis of uplift bearing capacity of pile based on ABAQUS

Abstract

The uplift bearing capacity of pile in soil foundation is mainly obtained by load test, which is time-consuming and low-efficiency. A small sliding model and the contact pairs in large-scale finite element software ABAQUS are used to simulate the friction between pile and soil, and a good fitting curve of pile foundation bearing capacity is obtained. According to the results of finite element software, the lateral friction of the pile is fully developed, and the stress of the pile gradually reaches the ultimate pullup capacity with the increase of pile displacement. The finite element software ABAQUS can be used to simulate uplift capacity of pile.
