摘　　要：本文应用泥石流非恒定流数学模型对泥石流平面运动进行了数值模拟，提出了泥石流堆积扇危险度评价的理论和方法。实例验证表明该法计算简便，稳健可靠，是评价泥石流堆积扇危险度的一种新途径。This paper deals with numerical simulation of debris flow inundation by applying mathematical model of the two-dimensional unsteady flow equations. The theory and methodology of evaluations on risk degree of de.bris flow were put forward.The example application and test show that this model is easily calculated and has a good stability and accuracy. It is a new method to evaluate risk degree of debris flow ondepositional fans.
