Other Abstract



[Objective]The aim of the study is to analyze the influence of mud on the moving ways,width and longitudinal distance and velocity of viscous debris flow on slope,and help to provide the references for disaster prevention.[Methods]The experimental model was built for viscous debris flow,and a series of model experiments were carried out through the device.The viscous debris flow composed of Chengdu clay mud and coarse particles.[Results]The adhesion force between the coarse particles increased,and the movement patterns changed from the inviscid debris flow to the viscous debris flow,and to the massive sliding with increasing mud density.The width and distance on slope decreased with increasing mud density.The migration process could be differentiated according to mud density.The velocity increases rapidly and the gradient is large when mud density was lower than 1.413g/cm~3.The migration process can be divided into two stages when mud density was higher than 1.413g/cm~3,the velocity increased slowly and the gradient changes little in the first stage but the velocity increased quickly,and the gradient changed quickly in the second stage. [Conclusion]The mud affects the movement pattern and the moving process of viscous debris flow.
