Abstract: In order to ameliorate the flow pattern of bending section of Tianbai hydroelectric station spillway in Kai County,to make the distribution of water flow be even and to improve the running stability,the optimization design of the curved bottom elevation of ultra high is put forward,according to the actual operation and conclusions got by some previous experience with similar projects. It can be concluded by the physical test that the optimization design can do well in abating the rapids shock,improving the bending period of flow regime,and improving the capacity of the downstream energy dissipation by adopting these engineering measures.

Key words: spillway, optimization design, bending section, flow pattern, flow distribution
