摘要
粘性泥石流破坏力极强,其主要破坏方式即对沟道的冲刷和淤积。本文通过室内实验的方法探究泥石流冲刷和淤积的规律。实验结果表明,泥石流冲刷深度跟泥石流沟道坡度的有很大的正相关性,随着泥石流沟床坡度的增加,泥石流冲刷越明显;泥石流冲刷深度随着泥石流容重的降低而增大。
Viscous debris flow is quite destructive,whose main devastating ways are scouring and depositing upon the gully bed.The article treats of the regularity of scouring and depositing of debris flow through laboratory experiments.The experimental results embody that there is a positive correlation between the scouring depth of debris flow and the gully bed's gradient of debris flow:the greater the gradient is,the more distinctive the scouring is;with the unit weight of debris flow decreasing,the scouring depth of debris flow will increase.
