摘要： 对某项目的基坑工程进行降水设计，利用管井井点降水,用Dupuit公式对基坑的涌水量进行计算，同时确定井点数量以及对降水井井位进行合理布置，并对基坑内水位降深进行了验算和降水时间进行预测，可供相关工程参考。

Abstract: This paper presents the dewatering design results for a deep excavation of an industrial facility. The proposed dewatering is a well point system. The required flow from the well point is estimated by using Dupuit Formula. The number of well points and their locations are carefully designed. The decrease in groundwater level and its required pumping duration are also predicted.

Key words: Excavation Dewatering, Dupuit Formula, Dewatering Depth, Well Points
