Abstract

Abstract

Using linear elastic finite element model for piles and pile cap, elastic-plastic finite element model for piles-surrounding soil under pile cap, linear elastic infinite element model for soil around pile group, and mounting interface element on the pile-soil interfaces, 3-D elastic-plastic finite element method is used to analyzing the pile-soil-cap interaction. It is found that under pile cap, the distribution law of the pile-top load is behaves as follow: the load exerted to the corner piles is largest to the side piles next, and to the middle pile lowest. The pile-top loads are uniformly distributed along with increasing load exerted on the pile cap, the skin friction of piles gradually develops from the pile-end towards the pile-top. The pile cap has a weakening effect on the skin friction of piles upside. To verify the results, a static load test on a nine pile group under pile cap performed. It is found that the obtained results from the proposed are matched for the results of the experimental test.
