摘　　要：通过断面物理模型试验,研究了赤吟橡胶坝的塌落度形态,测试在不同塌落度时,上游水位对应的泄流量。试验表明,同一塌落高度的橡胶坝,上游水位越高,下泄流量越大。研究不同流量和塌落度组合工况下,橡胶坝坝后消能的流态,优化闸后消力池和海漫段的布置,提出了赤吟橡胶坝今后合理的调度运行建议,可供类似工程参考。In this paper,through the physical model test of cross-section,the different collapse shapes of Chiyin rubber dam are analised,and the discharge of rubber dam corresponding to upstream water level is tested.The results show that the higher the upstream water level of rubber dam with the same collapse height,the higher the upstream water level,the greater the discharge.Furthermore,this paper studies the flow pattern of energy dissipation behind rubber dam under different combined conditions of flow and collapse shapes,optimizes the layout of stilling basin and apron section which is located downstream of the rubber dam,and puts forward reasonable regulation suggestions for Chiyin rubber dam in the future,which can provide reference for similar projects.
