粘性泥石流扇状地发展过程实验研究
Experimental Study of Fan Development Process of Viscous Debris Flow
摘要
Abstract
This study quantificationally discussed the phased characteristics of fan development process of viscous debris flow based on 3 groups, 106 indoor experiments under the condition of different debris flow densities, different slopes in the accumulation area and different channel slopes. Based on the average deposition slope of debris fan's cross-section and vertical-section, the development process of viscous debris fan can be divided into three stages. The first stage is characterized by rapid development in the longitudinal and transverse of debris fan.In the second stage, the longitudinal of debris fan will not develop and the debris flow will mainly develop in the transverse. The third stage is a longitudinal development stage. And the width of debris fan develops slowly in this stage.关键词
