武汉钰龙金融广场超深基坑工程设计方案选型

Design Scheme Selection of an Ultra-deep Foundation Pit in Wuhan

摘要:

以武汉钰龙金融广场超深基坑工程为实例，在结合常用的深基坑设计方案的基础上分别从基坑总体设计方案选定、基坑围护体系选定和设计、支撑体系选定、基坑降水选定、土方开挖方案选型和换撑方案的选定等方面进行探讨，并确定最终的基坑工程设计方案选型，即地下连续墙围护+3道内支撑+管井降水处理承压水的支护方案。

Abstract:

With an engineering case of ultra-deep foundation pit in Wuhan, based on the common-used deep foundation pit design scheme, the discussion was made on the overall design scheme selection, the selection and design of foundation pit maintenance system, selection of supporting system, foundation pit dewatering method, earth excavation scheme and support-changing plan. The final design scheme is underground continuous wall enclosure 3 internal supports confined water dealt with tube well dewatering.
