摘　　要：针对高水头、大单宽流量水利水电工程泄洪消能问题,介绍了一种多股多层水平淹没射流新型的泄洪消能型式,基于国内外研究基础,探讨了基本理论并进行了对比分析。结果表明,该消能方式流态稳定性好、临底流速低、消能率高,值得推广应用。Aiming at the problems of flood discharge dissipation for hydropower projects with high water head and large discharge per unit width,new-type flood discharge dissipation for multi-horizontal submerged jets is presented in this paper.Based on the research of energy dissipater in the world,its basic theory is summarized and discussed.The results show that the dissipater has good characteristics of stable flow pattern,low critical bottom velocity and high energy dissipation ratio,which is helpful for engineering applications.
