江坪河水电站面板堆石坝蓄水初期变形性态

江坪河水电站面板堆石坝填筑过程出现数次停工情况,坝体沉降特性与一般连续填筑的大坝有所差异,相当于老坝加高。蓄水前大坝最大沉降量小于类似工程,且沉降过程中存在的局部不均匀现象已经消除。蓄水前的坝体沉降以及面板监测成果显示,大坝填筑期间的停工过程对坝体变形控制是有利的。

Preliminary Study on Deformation Behavior of Jiangpinghe CFRD in Early Stage

During the filling process of the face rockfill dam of Jiangpinghe Hydropower Station, there have been several shutdowns. The settlement characteristics of the dam body are different from those of the general continuously filled dam, which is equivalent to the increase of old dam. The maximum settlement of the dam before impoundment is less than that of similar projects, and the local unevenness during settlement is eliminated. The settlement of dam before impoundment and the monitoring results of face slab show that the shutdown process during the dam filling period is beneficial to the deformation control of dam.
