某水电站真空激光准直系统变形监测数据研究分析

Research and Analysis on Deformation Monitoring Data of Vacuum Laser Collimation System in a Hydropower Station

文章以研究分析某水电站混凝土大坝坝顶真空激光准直系统运行期监测数据与时效、气温、降雨量及库水位等环境量相关程度为目的。基于所选取年份的坝顶真空激光准直系统实测数据,通过采用监测统计模型对监测数据与环境量进行拟合分析,得出位移变化与环境量的相关系数,验证了时效及气温为引起大坝变形变化的主要因素、降雨量及库水位为次要因素的结论,从而为其他真空激光准直系统的数据分析提供参考。

The purpose of this paper is to study and analyze the correlation between the monitoring data of the vacuum laser collimation system on the dam crest of a concrete dam of a hydropower station during the operation period and the environmental quantities such as aging air temperature rainfall and reservoir water level.Based on the measured data of the vacuum laser collimation system on the dam crest in the selected year the monitoring data and environmental quantities are fitted and analyzed by using the monitoring statistical model.The correlation coefficient between displacement change and environmental quantity is obtained which verifies the conclusion that aging and air temperature are the main factors causing dam deformation change and rainfall and reservoir water level are the secondary factors so as to provide a reference for the data analysis of other vacuum laser collimation systems.
