基坑开挖工程中渗流场的三维有限元分析

如何控制好地下水,减小其对基坑开挖和周围环境的负面影响,是基坑工程特别是深基坑工程设计与施工的重要组成部分。通过对基坑渗流场的三维分析,达到对基坑渗流场实际复杂情况的模拟,比较理想地反映基坑渗流场中等势线、流速矢量以及流量等渗流要素在不同条件下的变化规律,在一定程度上弥补过去对基坑渗流场研究的不足,为基坑工程止水防水设计提供一定的理论依据。

Three-dimensional finite element analysis of seepage fields in foundation pit

The control of groundwater and reduction of its negative influences upon foundation pits and surrounding environment are very important subjects in deep excavation projects. A series of 3D finite element analyses of the seepage fields in foundation pits were conducted. In this way, the simulation of actual seepage fields in complicated site and construction conditions was made in order to have a deep view of the general rules of seepages in foundation pits. Thus, the deficiency in understanding of the behavior of waterproof walls might be diminished, and more feasible and economic measures could be adopted for the design and construction of foundation pits.
