摘　　要：TB水电站引水发电系统土建及金属结构安装工程电缆电梯竖井开挖断面类型为矩形,断面尺寸较小且开挖深度较大的特点。其准确性和可靠性直接关系到竖井的施工质量,为保证开挖、衬砌体型和预埋件埋设精度满足设计要求,总结了小尺寸大高差矩形竖井施工测量技术和方法的应用。因此,对水电站电缆电梯竖井测量控制技术进行研究。The excavation section type of the cable elevator shaft for the civil engineering and metal structure installation of the TB hydropower station's water diversion and power generation system is rectangular,with the characteristics of small section size and large excavation depth.Its accuracy and reliability are directly related to the construction quality of the vertical shaft.In order to ensure that the excavation,lining shape,and embedded parts meet the design requirements,this article summarizes the application of small size and large height difference rectangular vertical shaft construction measurement technology and methods,and studies the measurement and control technology of the cable elevator vertical shaft in hydropower stations.
