针对柳树沟水电站导流洞的洞顶大塌腔，且不间断地掉石，施工中首先在塌腔下放置钢台车，在其保护下浇筑洞衬混凝土，后期向洞顶塌腔内采用固结灌浆的综合处理方案。经过近2a的运行，塌腔处理效果良好。
針對柳樹溝水電站導流洞的洞頂大塌腔，且不間斷地掉石，施工中首先在塌腔下放置鋼檯車，在其保護下澆築洞襯混凝土，後期嚮洞頂塌腔內採用固結灌漿的綜閤處理方案。經過近2a的運行，塌腔處理效果良好。

Concerning the big top collapse cavity of the diversion tunnel, Liushugou Hydropower Station, and the continuous falling of rocks and stones, the steel trolley is stationed under the collapse cavity.With the trolley protection, the tunnel is concrete lined.Later, the top collapse cavity is treated by the operation of consolidation grouting.After two-year operation, the cavity treatment presents good effect.
