Study on the Safety Influence of ExistingSubwaySationSructureBased on the Ecavation of Large Foundation Pit
Focusing on the safety influence of the existing subway station structure caused by the excavation of large foun-dation pit,this paper takes an actual project as an example,uses the Midas GTS finite element software to simulate and analyze the excavation of foundation pit,and studies the displacement and variation patterns of the wind pavilion and entrance structure during different excavation stages of the foundation pit,by comparing with actual monitoring data,the simulation results are consistent with the actual data,this calculation can simulate the deformation situation during construction.
