汶川震区清平乡文家沟泥石流灾害特征分析
|
摘要
2010年8月13日凌晨在四川省绵竹市清平乡暴发了16条泥石流,其中1条特大型(文家沟泥石流),1条大型(走马岭沟泥石流),9条中型,5条小型。清平乡场镇暴发的文家沟泥石流规模最大,泥石流冲出固体物质总量达310×104 m3,文家沟泥石流将清平乡老场镇的大部分区段淤埋。由于这场泥石流灾害发生在汶川地震高烈度区,是地震与降雨共同作用的结果,研究其形成原因,对于进一步认识强震区泥石流发育特征具有重要的意义。根据现场调查,从物源条件、地形条件、降雨条件分析了泥石流形成原因,并分析了泥石流成灾特征及成灾过程机制,以及泥石流运动特征等。
On August 13,2010,16 debris flows broke out in Qingping,Mianzhu,Sichuan Province,including one super large(Wenjia Gully debris flow),one large(Zoumaling debris flow),nine medium and five small ones.The largest Wenjia Gully debris flow discharged solid material of the total amount up to 310×104 m3 from the channel,which buried most districts of Qingping.Those debris flows happened in the earthquake high intensity zone of Wenchuan,resulting from the earthquake and the rainfall.Thus research on the forming reasons of debris flows is significant for a further understanding of the development characteristics.Based on the field investigation,we analyzed the reasons from the provenance,terrain and rainfall conditions,and the disaster characteristics and movement features of the flows.
