阐述了泥石流的主要特征。其中一节专门讨论泥石流触发，说明Takahashi（1978）的地质力学标准和最新的水文分布式模型。在第二部分，泥石流的流变学描述：由Bagnold的分散应力理论，稠密气体的动力学理论，以及最近的一些实验观察泥石流平衡。一节是专门的数学模型和最后一节讨论泥石流对策。关键词：对策;泥石流;动力学理论;数学模拟;流变学;风险缓解
The principal features of debris flow are described. One section is devoted to debris-flow triggering, accounting for the geomechanical criteria by Takahashi (1978) and for most recent hydrological distributed models. In a second section, the rheology of debris flows is described: the theory of dispersive stresses by Bagnold, the kinetic theories of dense gases, and some recent experimental observations about debris flows in equilibrium. A section is devoted to mathematical models and the final section discusses debris flows countermeasures. Keywords: countermeasures; debris flow; kinetic theories; mathematical modelling; rheology; risk mitigation
