摘要

雨季施工时基坑工程受暴雨入渗以及邻近河流水位涨落耦合作用

容易发生渗透破坏事故。基于裘布依(Dupuit)假定建立分层地基地下水耦合渗流方程

以此确定在暴雨入渗以及河流水位涨落耦合作用下基坑周边地下水位。同时基于渗流-应力耦合分析理论与Midas分析软件

以某基坑工程实例为研究对象

建立基坑工程渗流-应力耦合分析模型

对基坑工程渗流破坏现象进行分析研究

由此得出了对其它工程有重要参考价值的结论。

Abstract

The seepage accident is very easily occurred

when the excavation engineering has been constructed in rainy season and it is very easily influenced by the coupling effect of seepage duo to heavy rain and water level fluctuation of neighboring river. So a coupling seepage equation that based on the theory of Dupuit has been established for the ground water in the layered foundation. And then

the water table surrounding the excavation engineering has been determined on the consideration of the coupling effect of seepage duo to heavy rain and water level fluctuation of river. In the meantime

by means of the theory of coupling analysis of stress and seepage and the software of Midas

a model of coupling analysis of stress and seepage has been built for the specific excavation engineering and the seepage destroy characteristics of this project has been researched.
