摘　　要：排沙漏斗的工作原理是利用漏斗涡流排除进入渠道的推移质及悬移质泥沙。介绍了利用激光测速仪对排沙漏斗的三维流场的测试成果，分析了排沙漏斗的时均流特性和紊流特性及输沙机理。The working principle of the desilting funnel is to drain the bed load sediment and suspended load sediment which have entered into the canal by utilizing the funnel vortex flow. The measuring results of threedimensionalflowfield of the desilting funnel by using the laser velometer, are described. The timeaverage characteristics, turbulence characteristics and sedimentbearing mechanism of the desilting funnel are also analyzed.
