黏性泥石流冲刷沟床,会导致建筑物构筑物基础失稳,从而毁坏工程设施.本文通过室内水槽试验探究黏性泥石流沟床冲刷深度规律.试验结果表明:黏性泥石流沟床冲刷深度主要受沟床坡度、泥石流容重以及沟床物质容重的影响;黏性泥石流冲刷沟床的深度与沟床坡度成正相关,与泥石流容重或沟床物质容重成负相关;沟床平均冲刷深度与沟床坡度成线性正比关系,与泥石流容重成线性反比关系,与沟床物质容重的自然对数成线性反比关系.最后,分析得到黏性泥石流沟床平均冲刷深度经验公式.

It is very common that the buildings and engineering facilities collapsed due to the instability of their foundations caused by viscous debris flow in eroding gully bed. In order to explore the law of gully bed erosion depth,three groups of flume experiments were carried out. Experimental results show that (1) Erosion depth of gully bed mainly influenced by slope gradient,density of debris flow and density of gully bed materials;(2) Erosion depth of gully bed increases with increase of slope gradient and decreases with increase of density of debris flow or density of gully bed materials;(3) Average erosion depth of gully bed increases with the increase of slope gradient and has a linear relation, decreases with the increase of density of debris flow and has a linear relation and the increase of density of gully bed materials and has a logarithmic relationship. Finally,a prediction formula of the average erosion depth of gully bed due to vis⁃cous debris flow based on the experiment data was posed.
