Impact of Large Municipal Pipeline Renovation Project on Deformation of Existing Subway Tunnels
Based on the safety assessment of a large-scale municipal pipeline renovation project on the subways both in operation and under construction,FLAC calculation software is used to analyze the impact of foundation pit excavation,pipe jacking construction on subway tunnels,so as to compare deformation data and monitoring data,as well as put forward corresponding suggestions.The results show the maximum horizontal displacement and vertical displacement generated by the pipe jacking construction of DN1200mm large-diameter pipeline in the existing subway tunnels meet the control standards,which can provide reference for similar projects in the future.
