Abstract

Lots of built or building dams, especially the high arch dam, located in the Southwest China with abundant hydro-power resources. Most of these dams 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 at home and abroad, which have simple engineer structure, short construction period and the adaptability advantage on the changing discharge and Tail water depth. And the water plunge poor were always set downstream the dam body with large discharge and large power. 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.
