Analysis of the Impact of Foundation Pit Construction on the Operation of Subway Stations
The construction of foundation pits within the subway protection zone has a significant impact on the existing line structure and opera-tional safety.This paper taking the construction of adjacent foundation pits as an example,this study investigates the impact of foundation pit construction on existing subway structures through finite element analysis and monitoring data.According to the calculation results,the excava-tion and unloading of the foundation pit have a significant impact on the horizontal displacement and deformation of the existing line structure.The comparison between numerical simulation data and monitoring data shows that the simulation results are consistent with the actual situation,which can provide some reference for similar projects.
