摘　　要：漩涡是水利工程进水口前一种常见的水力现象,其生成和发展会对工程安全运行产生不利影响。认识漩涡的生成机理及其水力特性,对消除和利用漩涡具有重要意义。基于现有的研究成果,从漩涡的形成机制、水力特性和影响因素等方面出发,论述了进水口前漩涡问题的研究进展,明确了将临界淹没水深作为评判漩涡出现的依据,并分析归纳了现有的消涡措施。最后总结了现有研究中未能解决的问题,为进水口前漩涡的进一步研究提供了方向。Vortexes,which commonly arise at hydraulic intakes,have an adverse effect on the safety operation of the afflicted project.Understanding the generation mechanism and characteristics of vortexes is the key issue associating with the elimination and the utilization of vortexes.Thus,based on the existing research results,we discussed the research status of vortexes from the following aspects,including the generation mechanism,the hydraulic characteristics and the influencing factors.It is clarified that the critical submergence is the discrimination marker of the occurrence of vortexes.Meanwhile,the elimination methods of vortexes were analyzed and summarized.Furthermore,some imminent problems that have not been solved were put forward,which pointed out the direction for the further research of intake vortexes of praetical projects.
