摘　　要：为了改善开县天白水电工程溢洪道弯曲段流态,使断面内流量分布均匀,提高运行稳定性,根据其实际运行情况,结合以往类似工程的经验,提出了弯段底板高程正超高的优化设计方案。物理模型试验表明,采用这种工程方案可以很好地消减急流冲击波,改善弯曲段水流流态,提高下游消能能力。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.
