摘　　要：受地形条件限制,凤凰水库溢洪道泄水陡槽中设置了弯道段,由于冲击波的影响,弯道内水流横断面水深分布极不均匀,水流紊乱。为改善水流条件,提出了在陡槽弯道段底板布置斜底槛以消减冲击波的方案,通过水工模型试验表明,设计斜底槛能有效改善弯道水流流态。The arrangement in spillway of Fenghuang reservoir limited by topographical condition, and the bend section is built in chute. As a result of its influence, the discharge flow forms an asymmetrical shock wave, distribution of water depth in cross section of flow in bend chute is very uneven, and flow condition is seriously disturbed. In order to improve this condition, the designer suggests to arrange the slopping sill in bend chute, and through the hydraulic model test, the effect is proved good in improving water condition, and provided the basis for the project transformation design.
