摘要:随着地下轨道交通覆盖面积的扩大，许多建设项目地下结构施工距离地铁隧道较近，紧邻施工会扰动地铁隧道周围的土体，造成隧道结构发生变形和位移，影响地铁隧道结构服役性能。本文结合武汉市三镇中心项目，针对了TRD施工、地下连续墙施工和MJS土体加固三种紧邻地铁施工，描述了项目针对地铁隧道结构服役性态进行的自动连续监测方案，对地铁隧道拱顶沉降、道床沉降、水平位移和径向收敛四个自动连续监测项目进行分析，总结紧邻施工对地铁隧道结构服役性态的影响，为类似工程提供参考。
Abstract: The expansion of the coverage area of underground rail transit leads resulting that the construction of underground structures in many construction projects is closer to the scope of subway tunnel, which further brings about that the adjacent construction will disturb the soil around the subway tunnel and cause deformation and displacement of the tunnel structure, therefore affect the service performance. Taking the Wuhan Three Town Center Project as an example, this paper describes the automatic continuous monitoring scheme for the service behavior of subway tunnel structure for three adjacent subway constructions including TRD construction, diaphragm wall construction and MJS soil reinforcement. What's more, the paper analyzes four automatic continuous monitoring items, i.e., crown settlement, ballast bed settlement, horizontal displacement and radial convergence and finally summarizes the impact of adjacent construction on the service behavior of subway tunnel structure, which can provide a reference for the following relevant projects.
