粘性泥石流是指自然界中最典型的一种泥石流。作者依据野外原型观测和室内实验，证实该类流体具有带流核的层流特征并可用宾汉（Ｂｉｎｇｈａｍ）模型来表达。在此基础上推导其阻力和平均流速计算方法。我们认为，粘性泥石流作为不可压缩连续介质流体，符合质量、动量守恒律，因此可采用纳维－斯托克斯方程组来表达。考虑到它为拟线性双曲型偏微分方程组和阻力参数等特点，应用Ｌａｘ－Ｆｒｉｅｄｒｉｃｈｓ差分格式，选用云南东川蒋家沟的原型观测资料作为边、初值条件，编制计算机程序及数据库，而获得粘性泥石流水深、流速等要素的时空变化规律。该模型可以直接用于泥石流工程防治和量化的预测和警报 Viscous debris flow refers to the most typical nature of a debris flow. Based on field prototype observations and laboratory experiments, the authors verify that this type of fluid has laminar flow characteristics and can be expressed by the Bingham model. Based on this, the calculation method of resistance and average velocity is deduced. In our opinion, viscous debris flow, as an incompressible continuum fluid, conforms to the law of mass and momentum conservation, so it can be expressed by the Navier-Stokes equations. Considering that it is a kind of quasilinear hyperbolic partial differential equations and resistance parameters, the Lax-Friedrichs difference scheme is used to select the original observation data of Jiangjiagou, Dongchuan, Yunnan Province as the edge and initial conditions, and the computer program and database are compiled. The viscous debris flow depth, velocity and other elements of the temporal and spatial variation. The model can be directly used in debris flow prevention and quantification prediction and alarm
