根据野外泥石流浆体观测试验分析，通过对不同粒径沙颗粒的甘油沙浆流变试验，以及动摩擦临界浓度（Cvos）和极限浓度(Cvm)的实验研究，导出了反映泥石流浆体结构强度的屈服应力综合表达式，以便为泥石流高浓度、高速运动机理的探讨和泥石流防治工程的设计提供有科学依据的参数．
According to the analysis of field mud debris flow test, through the rheological tests of glycerin mortar with different particle size of sand particles and the experimental study of the critical concentration of kinetic friction (Cvos) and ultimate concentration (Cvm), the yield strength Stress comprehensive expression to provide scientifically based parameters for the discussion of the mechanism of high concentration and high speed movement of debris flow and the design of debris flow prevention and control engineering.
