交替题名A preliminary Study on the Material Composition of Debris Flows in Hunshui Gully
英文摘要The properties of a debris flow are mainly determined by the degree of freedom of solid particles forming the debris flow —— free ratio of porosity (ec), accoring to which, debris flows may be classified: ec<0.05-0.01 is viscous flow; 0.05-0.10<ec<0.37 subviscous flow; 0.37<ec<0.70 micro-viscous flow; and 0.70<ec<1.0 common sediment-charging flow. The mechanical composition of solid particles in viscous and subviscous flows is determined by the orginal earthe, but the mechanincal composition of the microviscous and common sediment-charging flows is closely related with the turbulence of the flow. Under natural conditions, the clay particles in a debris flow appear as aggrerates and the play the role of cohesion and lubrication. The concentration of clay particles plays an important part in forming the structure of viscous and subviscous flows. The water in a debris flow may be classified into tie water, enclosed free-water and gravity free-water. A viscous flow does not contain gravity free-water; a subviscous flows contains a lot of enclosed free-wate and a small amount of gravity free-water; and the two others do not contain enclosed free-water.
