【摘要】 重庆市轨道交通六号线一期五里店站—山羊沟水库区间隧道为开敞式TBM掘进,为了掌握重庆典型地质条件下TBM掘进对周边环境的影响,为重庆地铁以及其他类似工程提供借鉴,以该工程TBM掘进前300 m(里程K17+300～+600)隧道为依托对象,对TBM掘进区间隧道附近的房屋结构、桥台、围岩以及地表等进行了地表沉降和微振动的监测和对比分析。对TBM掘进的不同工况、不同地质条件的围岩及其支护进行了围岩变形、支护结构受力变形等的监测和对比分析,通过监测分析得出部分结论。更多还原

【Abstract】 Wulidian station-Shanyanggou Reservoir station tunnel section on the first phase of Line 6 of Chongqing rail transit.Settlement and slight vibration monitoring and analysis are made on the neighboring buildings,the abutments,the surrounding rock massed and the ground,with the construction of the tunnel section,300 m before TBM tunnelling,as an example,so as to recognize the influence of TBM tunnelling on surrounding environment in typical geological conditions in Chongqing.Monitoring and analysis are made on deformation of surrounding rock mass and support with different construction situations and different geological conditions of TBM tunnelling.更多还原
