摘要
以代表性泥石流为例,通过对泥石流的物质组成、启动方式以及降雨在泥石流过程中所起的作用进行详细的剖析.计算了泥石流的特征参数,对泥石流的危险性进行了评价,提出了降雨因素是的激发泥石流产生的外因,而陡峻的地形和流域内的松散物质储量则是形成泥石流的内因.
Using representative debris flow as an example, it's material composition, start mode and effect of rainfall were analyzed in detailed, the characteristics parameters were calculated, and the risk of debris flow was evaluated, the factor of rainfall is the external cause of debris flow, and steep terrain and loose material within the catchments reserves are internal causes of debris flow's formation.
