摘　　要：结合上海轨道交通4号线某站点基坑降水工程实例,分析工程地质条件和水文地质条件,通过对基坑底板稳定性进行分析,对基坑涌水量、单井涌水量进行计算,合理确定降压井数量以及降压井深度,结合以上各步骤完成工程降水方案设计。This paper combined with the foundation pit dewatering project of a station of Shanghai Rail Transit Line 4,analyzed the engineering geological conditions and hydrogeological conditions,analyzed the stability of foundation pit floor,calculated the water inflow of foundation pit and the water inflow of a single well,reasonably determined the number of depressurized Wells and the depth of depressurized Wells,and completed the engineering dewatering scheme design based on the above steps.

关 键 词：基坑稳定性分析 涌水量计算 降水井数量 深度
