| 英文摘要 | Abstract—Gully soil transportation is one of the mainly sources of river soil. As its special physical properties, debris flow can transport abundant of solid materials into main rivers in a very short time and take significant effects on the movement characteristics and evolvement disciplinarian of the main rivers. Based on a series of flume experiments indoor, this paper discussed the main affect factors of the soil transportation in debris flow gullies. The result indicated that the composition of grain size had changed obviously between the before and after debris flow flowed through the gully. Especially for sediment-laden flow and debris flow with high bulk density, the content of the course particles (d>2mm) increased a lot. At the same time, the scale of soil outflow increased as the increase of longitudinal slope of gully and the flow density while the formula is power function. |
