沙坝水电站碾压混凝土拱坝实测位移性态分析

Analysis on observed displacement behavior of RCC arch dam for Shaba Hydropower Station

本文介绍了贵州省沙坝水电站碾压混凝土双曲拱坝的变形监测布置情况,对工程下闸蓄水运行以来水平位移监测资料进行整理及多元线性回归分析,初步理清拱坝的整体变形规律和运行性态,为今后沙坝水电站大坝的安全运行管理提供参考。

The arrangement of the deformation monitoring of the RCC double-curvature arch dam for Shaba Hydropower Station in Guizhou Province is described herein, and then the horizontal displacement monitoring data since the impoundment of it are processed, while the multiple linear regression analysis is made on them as well ; from which the overall deformation law and the operation behavior of the arch dam are preliminarily obtained, thus provides a reference for the safety operation management for the dam in the days to come.
