芙蓉江牛都水电站工程泄洪消能设计

Design of Flood Discharge and Energy Dissipation for Niudu Hydropower Station on Furong River

针对芙蓉江牛都水电站工程洪峰流量大、河床狭窄的不利条件,采用坝顶表孔泄洪,表孔出口采用滑雪道+小挑坎面流消能方案,冲坑较浅并远离大坝,优化了坝体结构和取消下游消能防冲工程措施,确保工程安全的同时,降低了工程造价,对同类工程有较好的借鉴作用。

In view of the unfavorable conditions of large peak discharge and narrow riverbed of Niudu Hydropower Station on Furong River,the crest outlet of dam crest has been adopted for flood discharge and the scheme of ski-jump and small submerged bucket energy dissipation are adopted for the outlet of crest outlet.The scour pit is shallow and far away from the dam.The dam structure is optimized and the downstream energy dissipation and scour prevention measures are cancelled,which ensures the safety of the project and reduces the project cost.It has a good reference for similar projects.
