Abstract
In order to ensure the safety of adjacent tunnel structures during foundation pit excavation,this paper analyzes the influence mechanism of foundation pit excavation on the deformation of adjacent tunnels.Taking the deep foundation pit of a commercial building as the research object,the monitoring principles and monitoring plans of tunnel deformation(measurement point layout,monitoring frequency,early warning standards)are analyzed,etc.,and the monitoring results of crown displacement and side wall displacement at different positions of the tunnel structure are analyzed.Subsequently,a calculation model was established using the finite element software Midas/GTS to verify the monitoring results of tunnel deformation.The research results can provide certain reference for the monitoring of similar projects.关键词
