摘要
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。通过对设置排水措施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随降水井深度、间距以及抽水量等不同条件下的变化规律,从而在一定程度上弥补过去对基坑渗流场研究的不足,为基坑工程降水设计提供一定的理论依据。
The controlment of groundwater and reduction of its negative influences upon foundation pit excavation and surrounding environment become very important issues in deep excavation projects.This paper conducts a series of 3-D finite element analyses of the seepage fields of excavation with dewatering system.In this way,the simulation of actual seepage fields in complicated site and construction conditions were made in order to have a deep view of the general rules of seepages in foundation pit engineering,and illuminate laws of main physical quantities.Thus,the deficiency in understanding of the behavior of dewatering may be diminished,and,based on which,more feasible and economic measures can be adopted for the design and construction of foundation pits.
