摘　　要：放水洞是水库重要的建筑物之一,其功能决定了它位于坝的底部,工作状态不直观,出现问题不易发现。通过对放水洞常见问题的原因分析,提出了放水洞破坏的原因及免开挖处理方法,希望能对类似工程提供参考。　A water release tunnel is one of the most important buildings in a reservoir.Because of its function,it is lain in the bottom of a dam.We cannot observe its running conditions directly,so it is difficult to find out the problems in the water release tunnel when it does not run well.In the paper,through the analysis of the common problems of the water release tunnel,the cause for the damage and the treatment technique without excavation of the water release tunnel are put forward to provide references for similar projects.
