摘　　要：免棱镜全站仪应用于大型水电工程变形监测时的观测精度一直为关注的重点,将GPS、有棱镜、无棱镜三种测量模式同时应用于黄河拉西瓦水电站工程某滑坡体的变形监测中,并从平面和竖向位移等方面对各种观测结果进行对比分析。试验结果表明,三者监测结果一致,而徕卡TS30免棱镜全站仪精度高、测量可靠、工效高、危险性低,可代替GPS测量或有棱镜进行变形监测。It has been the focus of attention that the observation accuracy of total-station instrument without prism used in deformation monitoring of large hydropower project. This paper applies three measurement modes of GPS, with and without prism to the deformation monitoring of a landslide of Laxiwa hydropower project on the Yellow River. And then it makes comparative analysis in terms of the observation results of the plane and vertical displacement. The results show that three observation results have good consistency. So, the total-station instrument without prism Leica TS30 can be used in deformation monitoring instead, because of its high observation accuracy and measurement reliability, high effi ciency and low risk.
