摘　　要：为保证基坑开挖期间邻近隧道结构的安全,该文分析基坑开挖对邻近隧道变形的影响机理,以某商业建筑物的深基坑为研究对象,分析隧道变形的监测原则、监测方案(测点布置、监测频率、预警标准)等,并随隧道结构不同位置的拱顶位移和侧墙位移监测结果进行分析。随后,利用有限元软件Midas/GTS建立计算模型,来验证隧道变形的监测结果,研究成果可为类似项目的监测提供一定的借鉴。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.
