摘要：在富水砂层地区采用明挖法修建地铁,地下水处理至关重要。特别是在隔水层缺失，上部潜水与第1层承压水连通，基坑围护结构又未能有效隔断基坑外部水利联系的情况下，施工风险极大。本文结合南通地铁2号线某车站该情况下，基坑降水采取措施及监测结果进行分析阐述，能够为类似工程提供参考。
关键词：悬挂式围护 隔水层缺失 基坑 降水措施

Abstract: the treatment of groundwater is very important in the construction of subway by open cut method in the water rich sand layer area. Especially when the aquiclude is missing, the upper phreatic water is connected with the first layer of confined water, and the retaining structure of the foundation pit fails to effectively block the external water conservancy connection of the foundation pit, the construction risk is great. In this paper, combined with a station of Nantong Metro Line 2, the measures and monitoring results of foundation pit dewatering are analyzed, which can provide reference for similar projects. Key words: dewatering measures for foundation pit without suspended enclosure and aquiclude
