摘　　要：为研究淤地坝溃决后的洪水风险,通过总结归纳淤地坝溃决案例,分析淤地坝溃坝特征,以溃口尺寸、洪水痕迹为目标反演溃决流量过程,采用溃口扩展模型和水力学计算模型,推导针对淤地坝溃决洪水的计算模型,实现淤地坝溃决洪水快速分析方法 ,并结合西廒沟流域实际情况,对流域范围内的淤地坝溃坝洪水情况进行模拟分析,该方法计算快速、准确,可在工程实践中加以推广应用。In order to study the flood risk after the breach of check dam,through summarizing the case of check dam breach,analyzing the characteristics of check dam breach,taking the breach size and flood trace as the target to invert the breach flow process,using the breach expansion model and hydraulic calculation model,the calculation model of check dam breach flood is deduced,and the rapid analysis method of check dam breach flood is realized.Combined with the actual situation of Xiaogou Basin,the flood situation of check dam breach in the basin is simulated and analyzed.The method is fast and accurate,and can be popularized and applied in engineering practice.
