鉴于东风水电站运行以来，在发电和溢洪道下泄水流的长期冲刷下，大坝下游左、右两岸坡脚出现严重的冲刷淘空险情，为了不影响电站运行，采用了钢管桩或模袋混凝土立模、浇筑水下不分散混凝土、对底部石渣进行固结灌浆加固措施，取得了很好的效果。
鑒于東風水電站運行以來，在髮電和溢洪道下洩水流的長期遲刷下，大壩下遊左、右兩岸坡腳齣現嚴重的遲刷淘空險情，為瞭不影響電站運行，採用瞭鋼管樁或模袋混凝土立模、澆築水下不分散混凝土、對底部石渣進行固結灌漿加固措施，取得瞭很好的效果。
감우동풍수전참운행이래，재발전화일홍도하설수류적장기충쇄하，대패하유좌、우량안파각출현엄중적충쇄도공험정，위료불영향전참운행，채용료강관장혹모대혼응토립모、요축수하불분산혼응토、대저부석사진행고결관장가고조시，취득료흔호적효과。
In Dongfeng Hydropower Station , serious scour problem is found in the foot of the downstream slopes due to the long-term erosion effect of the water discharged from the station and the spillway .Thus, reinforcement treatment is carried out on the slopes .Steel pipe pile or mold-bag concrete is applied to form the mold .Underwater non-dispersed concrete is poured .Consolidation grouting is applied to strengthen the bottom stone blocks .Practice shows that the rein-forcement is successful .
