摘　　要：液压滑模以施工速度快、空间占用少、安全作业有保障、综合效益显著等特点广泛应用于竖井混凝土施工。测量监控在滑模施工过程中对混凝土结构外观质量的控制起着关键作用。以毛儿盖水电站调压井滑模施工为例,介绍了滑模施工过程中利用全站仪后方交会功能、配合激光导向束,方便、有效地对滑模的倾斜度和水平度进行检测与校正的过程,保证了测量精度和施工质量,提高了工作效率。Hydraulic slipform is widely used in shaft concrete construction because of its fast construction speed,less space occupation,safe operation and significant comprehensive benefits.Survey monitoring plays a key role in the control of appearance quality of concrete structure in the process of slipform construction.Taking the slipform construction of the surge shaft of Maoergai Hydropower Station as an example,this paper introduces the use of the total station resection function and the laser guide beam in the slipform construction process,which detects and corrects the inclination and levelness of the slipform conveniently and effectively,ensures the measurement accuracy and construction quality,and improves the work efficiency..
