摘　　要：针对典型泄水闸后直角弯道段和陡坡段产生的急流横比降及冲击波等影响工程安全运行的不良流态,通过物理模型试验研究手段,在泄槽内增设了多个组合的急流调控措施,并结合下游消能工优化,以水位、流速和流态等直观的水动力因素为优化指标,实现了对泄水闸后弯道段急流横比降的调控和陡坡段冲击波的消减,改善了消力池内水流流态,提高了整体消能效果,基本满足了设计要求。In view of the bad flow patterns that affecting the safe operation of the project, such as the sudden flow ratio drop and the shock wave produced by the right angle bend section and the steep slope section after the typical sluice, by means of physical model test, a number of combined jet control measures are set up in the slots, combined with the optimization of the downstream energy dissipator, the water level, flow velocity and flow state are straight. The hydrodynamic factor of the view is the optimization index, which realizes the control of the transverse flow ratio drop in the bend section after the sluice and the reduction of the shock wave in the steep slope section, improves the flow pattern in the stilling pool, improves the overall energy dissipation effect, and basically meets the design requirements.
