摘要：

采用数值方法研究了桩土接触面特性对水平受荷桩受力特性的影响，并通过对工程实例的分析验证了计算方法的有效性．实例分析表明，设置接触面对于正确模拟桩土受力特性有较大影响．计算所得的桩身弯矩和位移曲线表明，水平受荷桩的入土深度有个临界值，桩身过长对提高水平承载力无明显作用．

Abstract:

A numerical analysis method was presented to study the behavior of the laterally loaded pile considering the characteristic of the contact interface. The test data of piles under lateral loaded piles were used to analyze the effect of contact interface on laterally loaded piles. FEM was used to compare the results of the horizontal loaded single pile using different interfaces. The displacement curves of the pile computed show that as to horizontal loaded piles, there is a critical value of the depth of pile in soil, and the excess depth is useless.

Key words: laterally loaded pile, interface, numerical analysis, deformation
