摘　　要：对水电站边坡的位移、应力和地下水等进行监测,当GNSS静态测量的数据采集质量受地形影响较大和几何水准测量不具备条件时,采用高精度全站仪测量斜距、水平角和垂直角来监测水平位移和垂直位移,成为目前最可行的人工监测方法。本文结合TM30全站仪监测某水电站枢纽区高陡边坡的实例,讨论提高精密三角高程测量精度的措施,检验精密三角高程测量在高陡边坡垂直位移监测中的精度,供类似项目参考。When the quality of GNSS static measurement data collection is greatly affected by terrain and the conditions for geometric leveling are not available during the monitoring of displacement,stress and groundwater of the slope of the hydropower station,using the high precision total station to measure oblique distance,horizontal and vertical angle for monitoring horizontal and vertical displacement has become the most feasible manual monitoring method at present.Based on the example of TM30 total station monitoring a high and steep slope in a hydropower station hub area,this paper discusses the measures to improve the accuracy of precision triangular elevation measurement,and tests the accuracy of precision triangular elevation measurement in vertical displacement monitoring of high and steep slopes,which can provide a reference for similar projects.
