摘要: 根据高浓度黏性泥石流的观测资料,应用不同类型黏性泥石流的流变特性和流体结构的分类指标—流核比,对高浓度黏性泥石流堆积中的混杂层、筛积层和粗化层理结构进行了成因差异分析。侧重分析了砾石质点在高浓度黏性泥石流蠕动流场中作向上垂直运动的魏森伯效应,并在表面富集形成了筛积层的成因,及其它与粗化层结构的区别。

Abstract: According to observational data of viscous debris flows with hyper-concentration , distinct causes of formation for different graded bedding in debris flow deposits have been analyzed by use of its rheology and the ratio of flow plug . The paper specially analyzed that the gravel in squirm condition of hyper-concentration viscous flows would tend to have vertical motion due to the effect of Weissenberg , then they would form the bedding structure of the gravel accumulated at surface, and they are different from rough bedding structure.
