重庆市天生站和五路口站为暗挖双层岛式车站,结构复杂,对测量精度要求比较高。主要介绍了地下车站施工测量及监测方法,指出了测量和监控过程中应注意的重点及难点。地下暗挖车站施工时,按不同的施工部位、时段、不同的精度要求分阶段进行测量。同时,在车站施工过程中,对工程本身的应力、变形及周围建(构)筑物的沉降进行监测,确保施工安全和工程质量。通过对重庆市轨道交通六号线两个地下车站的施工测量控制,详细地说明了地下车站施工测量及监测的重点及难点。
Chongqing Tiansheng Station and Wulukou Station are double-inshored island stations with complex structures and high requirements on measurement accuracy. Mainly introduces the construction of underground station measurement and monitoring methods, pointed out the measurement and monitoring process should pay attention to the key and difficult. Underground excavation station construction, according to the different construction sites, time, different accuracy requirements of phased measurement. At the same time, during the construction of the station, the stress and deformation of the project itself and the settlement of the surrounding structures are monitored to ensure the construction safety and project quality. Through the construction measurement control of two underground stations on the 6th rail transit line in Chongqing, the key and difficult points of the construction and measurement of underground stations and monitoring are described in detail.
