摘　　要：为解决某大型水利库坝多孔溢洪道设计的不足之处并提出合理优化方案,以库坝为例,通过现场调查、测试获得多项水力、结构参数,并参照调查结果设计、展开室内库坝溢洪道多孔物理模型试验。试验结果表明:①现有溢洪道设计泄洪能力能够满足日常需求,但存在下游水流态差、水冠高等问题;②通过对比三种不同优化设计方案下水面水力水态特性,三种优化设计方案水冠高度较原设计分别降低了11.88%、2.25%及28.00%,均达到了优化效果,但采取第三种优化方案设计最佳。In order to solve the deficiencies in the design of a porous spillway for a large hydraulic reservoir dam and propose areasonable optimization scheme,taking a reservoir dam as an example,a number of hydraulic and structural parameters were obtained through field surveys and tests,and the indoor reservoir dam spillway was designed and developed based on the survey results.Porous physics model test.The test results show that:①the existing spillway design flood discharge capacity can meet daily needs,but there are problems such as poor downstream water flow patterns and high water crowns;②by comparing the hydraulic characteristics of the water surface under three different optimal design schemes,the three optimal design schemes The crown height has been reduced by 11.88%,2.25%,and 28.00%respectively compared to the original design,all of which have achieved the optimization effect,but the third optimization scheme is the best.
