摘　　要：介绍了振弦式沉降仪的工作原理和结构,并根据双沟水电站混凝土面板堆石坝振弦式沉降仪监测数据,分析了坝体沉降规律。针对测值中出现的周期性变化进行了探讨,分析其主要原因与水管内水温的变化有关。最后总结了振弦式沉降仪在混凝土面板堆石坝中应用时应注意的问题。The principles and structure of vibrating wire settlement gauge are described. Based on the monitoring data of concrete face rockfill dam of Shuanggou Hydropower Station, the settlement rules of the concrete face rockfill dam are analyzed. The causes for periodic changes in the measured values are discussed, and the main ones are related to change of the water temperature in the pipe. The problems of vibrating wire profiler used in the concrete face rockfill dam are reviewed.
