摘　　要：为验证建筑物泄洪放空洞泄流能力能否满足设计要求,通过数值模拟计算与整体水工物理模型试验2种方法,在数模计算的成果上进行物理模型试验验证。对不同洪水工况下泄洪放空洞水流流态、流速、水面线、压力、消能效果进行试验分析;对比研究数模结果与物模结果,验证泄洪放空洞体型布置及设计的合理性。根据试验结果提出合理的优化建议,为泄洪放空洞设计和运行调度提供参考。In order to verify whether the structure spillway hole discharge capacity can meet the design standard,the physical model test is carried out on the results of the numerical simulation calculation and the overall hydraulic model test,Using establish a three-dimensional mathematical model,the physical model test is tested in the results of numerical calculation.The flow state,velocity,surface line,pressure and energy efficiency of spillway hole under different flood conditions were tested and analyzed.The numerical results were compared with the test results to verify the rationality of the layout and design of spillway hole.According to the experimental results,reasonable optimization scheme is proposed to provide reference for the design and operation management of spillway hole.
