摘　　要：考虑到某一灾害事件可能会由多种源发灾害事件相互耦合作用造成,且次生灾害事件的演化过程可显著反映出整个灾害事件演化情况,通过引入"初始灾害事件"、"耦合灾害事件"等概念,并基于灾害演化网络,提出了灾害裂痕分析方法,进一步将该方法应用于2008年汶川8.0级地震灾害演化的分析中,从灾害裂痕范围和灾害裂纹深度两个维度分析了灾害演化的机理及其整体情况,最后总结出灾害裂痕分析方法的作用及意义,对开展防灾减灾及应急处置等工作起到一定的指导作用。A disaster event could be caused by mutual coupling of a variety of source disasters. In addition,the overall disasterevolution system can be obviously reflected by the evolution of secondary disasters. Therefore,in this paper,a disaster crack analysismethodology is presented based on disaster evolution network through introducing the concepts of initial disaster event and coupling disaster event. Furthermore,the mechanism and the overall situation of evolution of the earthquake disaster in Wenchuan 2008 are analyzed with this methodology from two dimensions,including the disaster crack range and the disaster crack depth. Finally,the function and significance of the methodology is investigated based on the above analysis of theory and case. Hopefully,this methodology will be of guidance for disaster prevention and mitigation,emergency treatment and other work related to emergency management.
