| 摘 要： | 分别采用瞬时溃决模型和逐步溃决模型对新疆克孜河泥石流天然坝的溃决洪峰流量及其向下游的演进情况进行了模拟分析，结果表明：瞬时渍决模型的计算结果与实测溃坝洪峰流量偏差较大，而逐步溃决模型的计算结果则接近实测值；采用逐步溃决模型计算时，计算时段的取值及溃口流量系数的取值对计算结果有一定的影响．

| Abstract: | The simulation analysis on the flood peak flow in dam-break and the evolution in the downstream of debris flow dam in Kezi River, Xinjiang is illustrated in the paper with instantaneous and gradual dam-break model. The results show that the theoretical deviation on flood peak flow in dam-break with instantaneous dam-break model is larger than measured value while the theoretical deviation with gradual dam-break model is close to the measured value. Therefore, the calculation of time and the flow coefficient by the method of gradual dam-break model has a certain impact on the result. |
