Abstract: With more than 80 thousand reservoirs, China has the largest number of reservoirs in the world, most of which are in operation. As an important infrastructure for national economy, the safety of reservoir dams has attracted much attention. Deformation monitoring is an important part of dam safety monitoring, which can directly reflect the deformation and displacement of dam. However, there are various problems with the deformation monitoring system of some reservoir dams during operation. In this paper, these problems and corresponding improvement suggestions are discussed, for reference.

摘要： 当前我国已成为世界上水库最多的国家，已有8万余座，大部分水库已经处于运行期。水库大坝作为国民经济重要的基础设施，其安全性备受瞩目。变形监测是大坝安全监测重要的一部分，可以较为直观地反映水库大坝的变形位移情况，但有些水库大坝运行期间，变形监测系统会出现各种问题。文章阐述部分水库大坝运行期变形监测系统出现的问题以及改进方案，以供其他单位参考借鉴。
