摘要
垂线监测作为大坝变形监测的主要手段,一直是大坝安全资料分析、评价的关键项目。简要介绍了小湾水电站大坝垂线监测布置情况,重点进行了初期运行阶段垂线实测资料对比分析。监测成果分析表明,大坝垂线系统布置合理,监测仪器工作性态正常,监测数据所反映的大坝位移变化趋势与水位相关性较好,垂线监测系统为大坝安全稳定运行提供了良好的保障。
The vertical monitoring is a primary mean to monitor dam deformation and is a key item for data analysis and evaluation of dam safety. The layout of vertical monitoring system in the dam of Xiaowan Hydropower Station is introduced and the monitoring data of vertical system in early stage are analyzed and compared. The monitoring results show that the layout of dam vertical monitoring system is reasonable, the operation behaviors of monitoring instruments are normal and the monitored dam displacement data are in good correlation with reservoir water level changes. The vertical monitoring system provides good protection to the stable and safe operation of dam.
