由于泥石流动力学过程的复杂性,其本构模型及数值模拟研究仍然存在众多的难点问题。本文根据大量的文献资料和实例研究,对目前泥石流本构模型和动力学模拟研究现状和存在的问题进行了综合论述,主要包括：（1）已有泥石流动力学本构模型原理及适用性问题;（2）已有数值模拟方法的实现及选择应用;（3）泥石流动力学复杂环境效应研究,复杂地形和水文环境条件下的泥石流应力分布、动能传递等。最后对泥石流动力学G IS模拟的前景进行了讨论。

英文摘要：

Due to the complexity of debris flow dynamic model and dynamics simulation. This review begins with sand numerical simulation of debris flow process. Next, process, difficulties exist on the study of its constitutive a survey of a number of literatures on constitutivemodelsome important aspects are discussed. They included ： （1） principle of existing constitutive models for debris flow and their applicability; （2） implement of numerical models and their application ; （3） effect of environmental factors on debris flow dynamicprocess, such as stress redistribution and propagationas a result of complex geomorphological and geohydrological conditions. Finally, the potential practicability of GIS simulation for debris flow simulationis discussed.
