摘　　要：对于水平受荷桩的分析,国内使用较多的是m法,但因不能考虑土的大变形和非线性特性,且相关规范或规程中给出的m值范围很大,给设计人员的取用带来很大困难。针对这一问题,本文基于p-y曲线法,就路堤堆载对邻近桥梁桩基的影响进行计算分析,其结果与二维有限元模拟结果的对比分析,表明本文提出的方法是可行的。M method was widely used to analyze the laterally loaded piles in China. However,it can not take large deformation and non- linear of the soil into account. It was difficult for designers to choose a suitable m value because of its great range in standard. To solve this problem,the influence of bridge pile foundation under embankment load based on p-y curve method was analyzed. The comparison between the analysis results and the two-dimensional finite element simulation results showed that the method based on p-y curve was appropriate.
