摘　　要：大顶子山航电枢纽自竣工运行至今,右岸消力池后方出现深度较大冲坑,本文参考国内类似工程经验,对冲坑成因、影响进行分析,通过对比选处理方案的分析论证,最终确定采用水下不分散混凝土+抛石+钢筋石笼的处理方案,并对设计方案具体工艺进行说明及模型试验论证。目前,项目已经实施,取得良好效果,可为其他类似工程提供借鉴和参考。Since the completion and operation of Dadingzishan Navigation-power Hub,there has been a deep scouring pit behind the right bank stilling pool.This paper refers to the domestic experience of similar projects,the causes and effects of the pit are analyzed,and through the analysis and demonstration of the comparative treatment scheme,the treatment scheme of underwater non-dispersive concrete+riprap+reinforced gabion is finally determined,and the specific process of the design scheme is explained and the model test is demonstrated.At present,the project has been implemented and achieved good results,which can provide reference for other similar projects.
