| 摘 要： | 针对淤积型水库溃坝洪水计算中是否考虑泥沙因素影响、产生怎样影响的问题，利用MIKE21中的水动力模块（HD）与输沙模块（ST）耦合，模拟淤积水库清水、浑水溃坝洪水演进过程，并通过溃坝峰顶流量值、溃坝最大水位值及溃坝洪水淹没历时的变化，分析泥沙因素对水库溃坝洪水影响。结果表明：库区泥沙可使下游各断面溃坝峰顶流量值变小，淹没历时变长；泥沙的中值粒径对峰顶流量、水位、淹没历时有影响。

| Abstract: | To the question whether considering the influence of sediment factor and what influence have in the process of dam-break flood routing in the sedimentation-type reservoir,the Hydrodynamic Module(HD) and Sand Transport Module(ST) coupling of MIKE21 were used to simulate the dam-break flood routing of clear water and turbid water.Meanwhile,the influence of sediment in the reservoir on dam-break flood was analyzed through peak flow discharge,maximum water level and dam-break flood duration changes.The result s... |
