摘　　要：通过对已建的一些采用表孔宽尾墩加消力池的重力坝调研资料及理论分析 ,表明宽尾墩可增加水流的三维特性 ,降低形成水跃的第二临界水深 ,从而可以使消力池底板抬高、池长缩短。因此 。Through investigating the prototype materials and theoretical analyses of some completed gravity dams in which the composite energy dissipation systems of stilling basins with flaring gate piers of the surface outlets have been adopted,the study results show that the flaring gate piers can play the roles of increasing the three dimension character of water jet ,decreasing the secondary conjugate depth of water jump,and thus the basin floor can be made higher and its length shorter.It is recommended that this kind of energy dissipation system may be used for the Zhaoshi Project.
