Abstract本文首先对泥石流运动的物理过程进行了分析,提出了泥石流运动二元性概念。然后从本概念出发,利用力的叠加原理及动量原理导出了泥石流的切应力方程,进而得出流速公式,最后利用实测资料对所得公式进行了验证,计算结果与观测数据吻合较好。
Other AbstractA viscosity-dispersion duality model is proposed to describe the mechanism of debris flow movement. Using the concept of the motion duality and the force superposition theorem and momentum law, unified debris flow resistance equation and velesity equation are developed, which are applicable to viscous, non-viscous and transitional types of debris flows. The validity of the resulting equations are evaluated by using field observation data. Uniform streanm is assumed for debris flow motion in derivation of the equation.
