| 中文摘要: |
| 大坝变形监测是大坝运行管理中一项非常重要的工作内容，而基准控制点是否稳定是大坝变形准确监测的前提.该文以萍乡山口岩水利枢纽工程控制网复测测值为分析基础，介绍了平面控制网的布设要求及外业观测时应注意的事项，对其基准控制点的稳定性进行了分析.通过复测测值与首次测值比较，测量控制点的固定角和固定边满足规范要求.基准控制点的稳定对提高大坝变形监测点的观测精度和准确预报大坝的安全运行提供了保障. |

| Dam deformation monitoring is a very important work in dam operation and management，and whether the benchmark control point is stable is the premise of accurate dam deformation monitoring.Based on the analysis of the re measured values of the control network of Shankouyan water control project in Pingxiang city，this paper introduces the layout requirements of the horizontal control network and the matters needing attention in field observation，and analyzes the stability of the reference control points.Compared with the first measured value，the fixed angle and fixed edge of the measurement control point meet the specification requirements.The stability of the benchmark control points can improve the observation accuracy of the dam deformation monitoring points and accurately predict the safe operation of the dam. |
