Characteristics of bedrock lithology in areas where debris flow material comes from

  • 摘要: 在一定区域内总体均匀的超强降水,并不会导致地形地貌条件大致相同的沟谷流域都发生泥石流,主要原因在于基岩岩性特征的差别。基岩构造总体较均一时,表部松散物的流失是持续渐进的;基岩为软硬相间的岩层,或者受到线性构造破坏,容易出现差异风化,表部物质呈脉动式剥蚀,可以为泥石流启动提供较好的物源条件。
    Abstract: In a certain region,the super precipitation of overall uniformity will not lead to debris flow in valleys under similar conditions of landform.Debris flow occurs mainly due to the differences of the characteristics of bedrock lithology.When the bedrock structure is overall uniform,loss of the department of loose form is continuous and progressive;if the bedrock is made of hard rock interbedded with soft rock,or is damaged by linear geological structures,the bedrocks may be weathered differently,and the department of the loose form is in a pulsatile erosion state,which preferably provide materials for debris flow.
