【 摘 要 】

Lots of high arch dam have the characteristics of "High head, Large discharge and Narrow river valley", therefore, the security researches of energy dissipation were always the focus in these hydro-projects. Statistically, the trajectory type energy dissipation is the most widely used in the built high arch dams, and the water plunge poor were always set downstream the dam body. However, the widely used protected plunge poor need large investment with the disadvantage of complicated operation and maintenance. Along with the construction of concrete high arch dam in the Southwest China, the river overburden and water cushion were deep in dam site, which is becoming a new characteristic of these hydro-projects. Accordingly, the deep water cushion can be used for the energy dissipation design, such as the "Reventment-Protected and Non-Bottom-Protected Plunge Pool", which has the advantage of more simplified project design and more economy investment.
