坝基反渗水压力及其对混凝土面板的破坏作用

Inverse seepage water pressure on dam foundation and its destroying effect

松山混凝土面板堆石坝是松江河水电站松山引水枢纽头部工程。大坝一期混凝土面板和一期面板的补强面板分别遭受坝基反渗水压力的破坏。本文对于反渗水压力的形成、力值大小及其破坏作用作了较详尽分析,同时提出了消减反渗水压力措施。

Songshan concrete face rockfill dam is the head project of Songshan diversion works for Songjianghe water power station. The first concrete face and its strengthening face are destroyed by the inverse seepage water pressure on dam foundation. The paper analyses the formation, the magnitude, the destroying effect of the inverse seepage water pressure and puts forward the measures to reduce the inverse seepage water pressure.
