本文涉及泥石流建模的力学方面，并将侧重于稳定的，充分发展的流动。在简要回顾了为模拟这些流动而设计的本构方程的类型之后，如粘塑性宾汉模型、Bagnold分散应力模型和广义粘塑性模型，我们将描述一些颗粒流动动力学理论模型和“颗粒动力学”计算机模拟。
The paper deals with the mechanics aspects of the modelling of debris flows and will focus on steady, fully developed flows. After a brief review of the types of constitutive equations that have been devised to model these flows, such as the viscoplastic Bingham models, Bagnold dispersive stress models, and generalized viscoplastic models, we shall describe some granular flow kinetic theory models and 'granular dynamics' computer simulations.
