Analysis of the Influence of Deep and Large Foundation Pit Excavation on the Existing Subway Structure
In view of the influence of deep and large foundation pit construction on the safety of existing subway struc-tures,this paper takes the actual project as an example,analyzing the influence of foundation pit excavation on existing subway structures through theoretical analysis and three-dimensional numerical simulation.The re-sults show that the excavation of foundation pit will cause deformation and non-uniform settlement of subway structure.Therefore,only by strictly following the design plans and adopting reliable methods during construc-tion can the safety of existing structures be guaranteed.
