Abstract

Abstract

A case of a deep foundation pit project in soft-soil area of Shanghai has been studied.Focusing on the environmental characteristics of a shallow foundation pit adjacent to one side of this deep foundation pit,the design idea of foundation pit retaining structure is proposed,and the brace type with large angle brace are introduced in detail,which is more conducive to the overall deformation control of deep foundation pit.Through the analysis and research of the monitoring results,the safety and rationality of the design are proved.The experience obtained from this case is of reference significance for similar projects.
