Abstract
In this study, we research the rheological properties of debris flow. The main topic is to develop the suitable rating formula of flowing phenomenon rheological parameters for rheological experiments. Theoretically, we start from Bingham and Green(1920). We separate the fluid into two layers: shear layer and plug layer, and derive the governing equations and boundary conditions, respectively. Through normalization, we can analyze each equation and solve the rating formula. In experiments, we will use the homogeneous materials basically.We Excerpt the experimental data of weight percentage concentration 30%~50% from Liu and Ai(2009),Liu and Lin(2012).Finally, from the rheological parameter rating formula with the experimental data and the theoretical development, we can calibrate the rheological parameters of Bingham mode. We will verify the correctness and feasibility of the rheological parameter rating formula, to provide future researchers in related rheological experiments and the use of reference.
