采用自己最新研制的泥石流流变仪 ,测试自然界活泥石流体的样品 ,发现粘性泥石流体在低速率受剪时具有应力过冲和剪切稀化等特征。这些特征的讨论和认识 ,为进一步深化泥石流模型理论研究奠定了基础

Under support of the latest rheometer designed and made by the author, the rheological characters of natural debris flow were measured. According to the measured data, this paper preliminarily discussed the characters of viscous debris flow at low shear rate. And this study find that overstress effect and shear dilution phenomenon characterize the viscous debris flow in the Jiangjia Ravine, China. All of these have laid the foundation in a certain degree for further study on theory of debris flow model.
