摘要
采用悬栅（板）消能可有效解决陡坡急流冲击问题，并已在实际工程中成功应用．采用多普勒激光测速系统对流场进行全面测试，结果分析表明，悬栅（板）消能可显著降低凹岸水深，从而达到稳定和平顺水流的目的．与人工增加陡坡糙度相比，具有适应性强和消能效果明显的特性．
The supercritical shock wave was obviously improved with the application of hanged-grid & hanged-plate in the slope-curve channel. The new dissipator is really used in practice and is successful. In this paper, the Doppler-laser velocimeter was employed to measure the velocity field around the hanged-grid & hanged-plate. The stability and uniformity flow appeares. This kind of dissipator has the better dissipated energy ratio and adaptability than those conventional types as increasing roughness under the floor. These experimental results are helpful for learning the mechanism of hanged-grid & deflector plate dissipation.
