条形基础与上部结构、地基的联合受力分析

Strip Foundation,Superstructure and Soil Interaction Analysis

本文以一六层５跨平面框架为例，用非线性有限元法分析了七种（六类土、一种岩石）地基条件下，考虑上部结构－条基－地基三部分共同作用时，条基基底反力、沉降和底板弯矩。将得出的弹塑性结果与弹性结果相比较。对如何合理地设计条基提供了参考。

This paper is based on a six-storey,five-span plane frame building. Using nonlinear finite element analysed seven foundation cases (six cases for soil. one case for rock).Considering superstfucture-strip foundation-soil interaction,the pressure distribution,settlement and bending moment of the strip foundation is obtained in this paper. In the meantime, compared the elastoplastic results with the elastic results. This paper provided the reference for rational design of strip foundation.
