摘要: 以杭州火车东站扩建工程、综合体西广场、地铁盾构隧道及站房、周边配套设施等多个紧邻集中施工的大型深基坑工程为背景,根据特定场地土质条件,通过确定合理施工时序、制定自立式围护结构设计原则,设置多个独立封闭的止水帷幕等,得到了一系列交界面关键控制技术,保证了特大型多个基坑工程如期顺利完成。

Abstract: Multiple adjacent large and deep excavations are closely related and largely affected each other by centralized construction. Through the determination of reasonable construction sequence and the design principle of self retaining structure, A series of interface retaining structure control technologies are obtained by setting up multiple independent closed curtains. The construction is successful with the deformation of metro tunnel in the range of allowable values.
