【摘要】 用线性插值函数来逼近土对桩的各种约束反力沿桩入土深度的分布，采用有限元方法和p-y 曲线对水平承载桩进行了桩－土共同作用的非线性分析研究，得出一个新的桩－土相互作用的单元计算模型．推导了桩－土相互作用的非线性单元刚度矩阵，并编写了相应的有限元程序．更多还原

【Abstract】 Linear interpolation function is used in this paper to approximate the soil’s antiforce to the pile, the horizontally loaded pile-soil interaction is studied by finite element method and p-y curve, in this way a new pile-soil interaction element calculated model is designed. In this paper, a nonsymmetry element stiffness matrix is deduced, and write the relevant finite element program.更多还原
