摘　　要：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。Tiansheng Station and Wulukou Station of Chongqing are double-layer mined underground metro station.The complex structures of these stations impose high requirement to the measurement precision.The paper mainly introduces the measuring and monitoring methods of these underground stations,points out the key points and difficult problems that should be paid attention to.During construction of the mined underground metro station,measurements should be done in different phases according to different construction positions,different construction phases and different precise requirements.At the same time,stress and deformation of the station as well as its adjacent buildings should be monitored for all construction process to assure construction safety and engineering quality.
