水库溢洪道多级消能优化研究

Research on reservoir spillway multistage energy dissipation optimization

水电站多具有长泄水道、大落差发电特点,对于这类电站单级消能工已经不能满足安全和经济要求,因此,宜采用多级消能。本以大河边水库为研究对象,针对溢洪道原设计方案中的不利水力现象进行了方案修改,取得了良好效果。

Hydropower station is mostly characterized by long sluiceway and big drop power generation. Single-stage energy dissipation work of the power station can not meet requirement on safety and economy. Therefore,multi-stage energy dissipation can be suitably adopted. In the paper,Dahebian Reservoir is adopted as a research object,plan is modified aiming at adverse hydraulic phenomenon in original design plan of spillway with excellent effect.
