| 摘 要： | 利用GPS与水准测量相结合对某水库大坝表面变形进行了多期监测，采集了大量的观测数据。通过内业计算、严密平差得到该水库的各个变形点的三维坐标，并与上期资料相比较获取坝点的形变量，最终通过计算、分析给出水库中坝、东坝及西坝3个坝体的稳定性参数。

| Abstract: | in the paper, the surface motion of reservior＇ s dam is multi -stage monitored using GPS and leveling, and collected a large amount of observational data. Computing the data to obtain three dimensions coordinates of every deformation point in the reservoir＇ s dam, contrasting the data of last time to obstain the deforma- tion quantity of every point. In the end, the stability of middle dam, eastern dam and northern dam are obtained by computing and analysis. |
