摘要

在桩与桩侧土界面引入接触单元模型，并采用参变量变分原理及基于此原理的参变量二次规划法，对接触单元刚度矩阵进行了推导。模型计算结果与实测比较表明，接触单元能较好地模拟桩与土之间的剪力传递和相对位移。

Abstract

The contact element model is introduced to simulate the pile-soil’ s reciprocity

then the paper derived the contact element stiffness matrices by adopting parameter variable’s variational principle and parameter variable’s second programming method.With comparison of computing result and test in situation

it shows that the contact element model is suited to simulating the pile-soil’ s shear force transmission and relative displacement.
