粘性泥石流体具有粘聚力和内摩擦角,其剪切强度基本符合Coulomb公式.按颗粒散体流动模型推导出了粘性泥石流阻力方程与匀速运动方程.运动方程经实验和野外原型观测获得了验证,表明建立的运动方程与实际相符,是可信的.也可以阐明迄今尚未得到解释的、实际发生的某些粘性泥石流具有很高流速的机理. The viscous debris fluid has cohesion and internal friction angle, and its shear strength basically complies with the Coulomb formula.The viscous debris flow resistance equation and the uniform velocity equation are deduced according to the granular flow model.The kinetic equation is validated by experiments and field prototype observations , Indicating that the established equations of motion are plausible and that it is possible to elucidate heretofore unexplained mechanisms that actually occur for certain viscous debris flows with very high velocities.
