都江堰八一沟8·13泥石流的形成条件分析
|
摘要
2008年汶川地震产生的崩滑体曾造成了巨大的人员伤亡,地震后,这些崩滑体成为泥石流活动的最主要物源,极大地助长了汶川地震后次生灾害的发生。为了有针对性地开展防灾工作,以2010年8月13日都江堰八一沟泥石流为研究对象,采用野外调查与遥感解译的方法,从泥石流形成的地形地貌、物源与水源三大基本条件,详细分析了八一沟8.13泥石流形成条件,发现此次形成条件十分有利于泥石流的暴发,同时,该分析方法对类似条件的泥石流沟具有一定的借鉴意义。
The large number of collapse and landslide triggered by the 2008 Wenchuan earthquake had caused a lot of casualties.After the earthquake,the deposits from the collapse and landslide became the primary source for debris flows,which greatly increased the occurrence of earthquake-induced hazards.In order to carry out the hazards prevention work,this paper selected the 8.13 debris flows in the Bayi Gully as the example to investigate its initiation conditions.Field investigation and remote sensing measures were used,and three fundamental conditions to initiate the debris flows were analyzed including landform,soil source,and water source.The results suggested the initiation conditions were favor for the occurrence of debris flows.Additionally,the analytical method applied in this paper can provide references for the study of debris flows under similar conditions.
