摘　　要：分析水布垭水电站坝址区下游庙王沟排洪沟存在的主要问题,从设计、施工及管理维护三方面探讨了排水、防沙、消能防冲三方面的综合治理措施。经汛期检验,排洪沟的改造有效减弱了强降雨的不良影响,保证了电站工区道路的正常通行,提高了对坝址区下游护岸及弃碴场的稳定性。The comprehensive treatment of Miaowanggou flood discharge ditch in Shuibuya Hydropower Station is introduced.Firstly,existing problems of the flood discharge ditch are analyzed.Then,treatment measures in the design,construction and management are proposed considering the water discharge,sediment control,and energy dissipation and erosion control issues.Practical operation of the flood discharge ditch during the flood season shows that the treatment is successful as it effectively reduces the adverse effects of heavy rainfalls,ensures the normal traffic of the roads in the work areas,and improves the stability of the revetment and the spoil area at the downstream of the dam site.
