摘　　要：水电工程外部环境的改变,要求对原有建筑物进行适当的改造,以保证工程安全,提高工程效益。以黄龙滩水电站非常溢洪道改造工程为实例,通过分析改造的必要性和可行性,对拟定的3个改造方案进行比选,最终选定弧形闸门、预应力闸墩为推荐方案,较好地解决了宣泄小流量的工程难题。Due to the changes of the external environment of hydropower projects,proper reconstruction of original structures are usually needed to ensure the safety of the project and also improve the project benefit. The reconstruction of the emergency spillway in Huanglongtan Hydropower Station is introduced. Three reconstruction schemes are compared by analyzing the necessity and feasibility of the schemes. Finally,the scheme with radial gates and pre-stressed piers is selected as it solves the small discharge flow problem.
