Abstract

Abstract

Taking the Hanjiang Bridge pile foundation project of Xiamen-Shenzhen Passenger Dedicated Line as the background,static load model test was adopted to study the load-settlement and pile's stress ratio characteristics of vertical pile foundation and inclined pile foundation.The results showed that the load-settlement curve of the inclined pile foundation showed non-linear prior to the vertical pile foundation,and settlement of the inclined pile foundation was smaller than that of the vertical pile foundation at the early load phase.The pile's load sharing amount of the vertical pile foundation and the inclined pile foundation was increasing with the upper-load's adding,but the pile's load sharing ratio of the vertical pile foundation increased monotonically while that of the inclined pile foundation turned increasing first and then reducing.Affected by the pile spacing that increased from top to bottom,the masking effect of pile decreased at the lower part of the inclined pile foundation then the extrusion effect of soil was enhanced, which is the main reason of the different load-bearing characteristics of two sorts of different pile foundations．
