| 摘 要： | 粘性泥石流运动模型的研究因受实验条件的限制，还很不完善。国内外学者应用较多的５种模型都有一定的适用性，但也都存在不同的缺陷。本文应用粘性泥石流土样中的细颗粒和粗颗粒进行流变实验，不仅得到了粗颗粒在浆体中的沉降特性和泥石流体的流变特性，还研究了粘性泥石流运动模型及其参数。所提模型能很好地反映泥石流体的流变特性，较现有的５种模型能更好地描述粘性泥石流。

| Abstract: | The research on movement model of viscous debris is not perfect due to ristriction on experimental condition. Each of five models used by scholar in home and abroad is only appropriate tosome range and shows some shortcomingS. In this paper, the subsidence characteristic of coarse granulain slurry and the rheological characteristics of debris are studied and the movement model of viscousdebris and its parameters are determined. The model is better in describing rheological characteristics ofviscous debris flow than former models. |
