摘要

提出了一种刚性基础-桩-土共同作用非线性分析更为简便的近似方法。刚性基础基底单元（桩或土单元）本身受力变形的非线性关系采用静载试验得到的Q-s曲线，这种单元自身非线性及单元之间线弹性共同作用，可同时用迭代法计算。算例表明，这种方法方便、实用，能较好地反映桩、土非线性特性对基础受力变形的影响。

Abstract

A approximate method for analyzing rigid foundation-piles-soil nonlinear interaction is presented. Q-s curves from static load tests is applied to nonlinear load-settlement relation of pile or soil itself unit. The nonlinear property and linear elastic interaction between two units can be simultaneously computed by iterative method. The analysis of numerical examples show that the suggested method is simple

convenient and efficient.
