Analysis on the Influence of Parallel Foundation Pit on Adjacent Subway Structure Based on 2# Tunnel of the Shiziyang Link Project
The influence of foundation pit excavation of 2# tunnel of the Shiziyang Link Project on air shaft and section of Guangzhou Metro Line No.18 is analyzed by creating 2D and 3D finite element model.The rationality of the design of foundation pit retaining structure is verified,the difference between 2D model and 3D model is analyzed,and the relationship between the displacement of existing structure,the excavation depth of foundation pit and the type of subway structure are studied.The research can provide reference for the analysis of subway structure adjacent to foundation pit.
