天花板水电站泄洪消能建筑物设计

天花板水电站泄洪消能建筑物采用坝身泄洪,遵循"水舌平面分散、纵向分层拉开、总体入水归槽"的原则,未设置水垫塘及二道坝.经水工模型试验验证,鼻坎布置合理,消能效果较好,不仅节省了工程投资,也缩短了工期.天花板水电站泄洪消能建筑物的设计方案,对规模和条件类似工程泄洪消能建筑物的设计具有一定的借鉴意义.

Design on Flood Discharge and Energy Dissipation Structures of Tianhuaban Hydropower Station

The flood discharge and energy dissipation structures of Tianhuaban Hydropower Station are arranged in dam body according to the nappe design principle ofPlane-dispersed,vertical-stratified and overall returning into the channel,and do not set the cushion pool and subsidiary dam.The hydraulic model tests show that the arrangement of bucket lip is reasonable and the energy dissipation is better.The design not only saves the investment,but also makes the construction ahead of schedule.The design practice can ...
