Response prediction method for tension piles considering progressive soil deformation

Abstract

This paper presents a analytical approach for the analysis of the response of a single pile and pile group subjected to tension load by the load-transfer approach. The shaft displacement of a tension pile is assumed to comprise the relative displacement of disturbed soil around a pile and the elastic vertical soil displacement. Considering the interactive effects among piles, a new load transfer function of the individual pile in a pile group is proposed. In addition, an effective calculate method is developed for analyzing the response of a single pile and a pile group subjected to tension load. Comparative analyses are then performed to demonstrate the veracity of the proposed method. The comparative analysis results show that the proposed approach is reliable for the analysis of the response of single piles as well as pile groups subjected to tension load.
