| 摘 要： | 我国已建成的特高拱坝如溪洛渡、锦屏一级等,在初期蓄水过程中均表现出了谷幅收缩的异常现象,然而均没有对开挖卸荷期间谷幅变形情况进行观测研究。通过对白鹤滩水电站开挖期间谷幅变形监测进行分析,为同类型高拱坝变形监测提供相关参考依据,同时为后续蓄水初期谷幅变形监测分析提供相关基础保障。

| Abstract: | The super-high arch dams in China,such as Xiluodu and Jinping,have exhibited anomalous phenomenon of valley shrinkage during the initial impoundment.However,there is no observation on the deformation of the valley during excavation unloading.The deformation monitoring of the valley are analyzed during the construction period of Baihetan Hydropower Station,and provides relevant reference for the deformation monitoring of the same type of high arch dams.At the same time,it provides relevant basic guarantee for the monitoring and analysis of valley deformation in the initial stage of water storage. |
