摘　　要：北京电视中心基坑降水采用以管井井点抽水为主、局部渗井井点为辅,抽渗结合、配合区域明排水的施工方法,在基坑外侧布置大口径降水井86口,基坑内疏干井10口,基坑内加深坑抽渗减压井14口,有效地解决了降水问题。The main dewatering method adopted in Beijing Television Center Project is pipe well point assisted by local seepage-well point. 86 dewatering wells of big diameter are arranged along outside the construction pit, 10 drainage wells inside, and 14 deep pit decompression wells in the pit. Dewatering problem is therefore resolved effectively.
