摘　　要：本文在介绍GNSS变形监测原理、应用情况及其优点的基础上,以旁多水利枢纽工程为例分析了GNSS变形监测网的布置情况,并对变形监测成果进行对比分析,结果显示:枢纽大坝水平位移同上游库水位有很好的相关性,垂直位移量及速率符合土石坝固结沉降一般规律。该工程GNSS变形监测的成功应用可为大中型水利工程外部变形监测提供借鉴,同时也为GNSS在垂直位移监测方面的应用提供实证。On the basis of introducing the principle,application and advantages of GNSS deformation monitoring,the analysis of the arrangement of GNSS deformation monitoring network taking Pang Duo hydro-junction as an example.This paper also analyzed the deformation monitoring results,which shows that the horizontal displacement of hydro-junction dam has good correlation with the upstream reservoir water level and the vertical displacement and rate conform to the general rule of the consolidation settlement of earth-rock dam.The successful application of GNSS deformation monitoring in this project provides a useful reference for the external deformation monitoring of large and medium-sized hydropower projects,and also provides a demonstration for the application of GNSS in vertical displacement monitoring.
