摘要
Abstract
The giant debris flow in Wenchuan earthquake zone spread along the main central fault belt (Yingxiu—Beichuan Fault) and the fault belt behind the mountain,with zonary and linear distribution.The paper selected 21 typical giant debris flows therein to make analysis in such manner that,on the basis of geological environmental conditions to form geological hazard and its basic characteristics,and in combination with basin area,total sources,source distribution modulus and concentration,and runout scale,the distribution and activity characteristics of the debris flow were analyzed comprehensively.Finally,the basic laws of sources,water supply and trigger condition of post-earthquake giant debris flow,were concluded.关键词
