Abstract

Abstract

The project of shenzhen east gate No.61 compound is located in east gate commercial street,Luohu,Shenzhen,it is adjacent to the subway and existing shallow foundation buildings.The depth of excavation is 17.15 m and 18.60 m.According to surrounding environmental requirements and geologic conditions,various types of bracing system such as secant pile,punching pile,rotary jet grouting pile,internal supporting system and anchor cable were selected.The construction of deep excavation were seriously simulated by the three-dimensional numerical simulation method.Based on the results of numerical analyses,foundation pit deformation and its impact on subway were studied.Design and construction has been completed and proved to be effective,which provide valuable references for similar projects in the future.
