【摘要】 对细颗粒层间滞水水文地质条件下的深基坑降水方法进行了理论分析和设计施工研究，提出采用管井和自渗砂井联合降水的设计施工方法，并在北京市望京地区进行了工程实践，解决了深基坑层间滞水的降水难题。更多还原

【Abstract】 The dewatering method of deep excavation is analysed in the theory and design and construction under the hydrogeology circumstances with the particle confined water. The dewatering design and construction methods combined by the pipe well and self-seepage sand drain are proposed and experimented at Wangjing District,Beijing. The dewatering puzzle is solved for the confined water of deep foundation pit.更多还原
