【摘    要】：针对暗挖地铁车站传统地面管井降水施工受到复杂条件的影响，难以实施或形成封闭降水条件的难题，以北京地铁某暗挖车站为例，通过精细化分析车站周边环境条件及工程地质、水文地质条件，采用导洞降水井、单边减压降水、倾斜井点疏干降水等综合降水方案处理地下水。

【Abstract】：In view of traditional surface pipe well dewatering construction of underground stations is affected by complex conditions， so it is difficult to implement or form closed dewatering conditions， taking a underground station of Beijing Metro as an example， through a refined analysis of the station's surrounding environmental conditions and engineering geological and hydrogeological conditions， the comprehensive dewatering schemes such as pilot tunnel dewatering wells， unilateral decompression dewatering， and inclined well point dewatering dewatering are adopted to treat the groundwater.

【Key words】： metro; underground excavation station; groundwater;dewatering in pilot tunnel
