| 摘 要： | 采用有限体积和有限差分相结合的数值方法,建立了一维溃坝水沙数学模型,基于新集水库库区泥沙淤积演算成果,分别对其在蓄水初期进行纯水溃坝计算和淤积一定年限以后进行水沙溃坝计算,合理地模拟了溃坝后断面流量和水位变化过程、河床冲淤变形等结果,并分析了泥沙因素对溃坝洪水波传播的影响. |
| 关 键 词： | 溃坝 数值模拟 泥沙 洪水传播 |

| Abstract: | The finite volume method and finite difference method are adopted to establish 1D dam break flow and sediment numerical model.Based on the deposition data of Xinji reservoir,such model is used to simulate the flood routing process with scouring and aggrading process of sediment;and the influence of the sediment on the routing process of dam break flood is also analysed. |
| Keywords: | dam break numerical simulation sediment flood routing |
