基于AHP的高处坠落事故脆性分析

高危建筑行业施工作业中高处坠落事故居于“五大伤害”事故之首。以高处坠落事故的发生为研究对象，由层次分析法得出导致事故发生的各因素的相对重要度的排序向量，根据复杂系统的脆性理论，通过脆性激发度的定义，对高处坠落事故进行了脆性分析。结果表明，使用不安全设施、无防护措施、强度不够和处于不安全位置这四种因素是导致高处坠落事故发生的主要脆性源。研究结果为建筑行业事故防控体系的建立提供一种新的途径和思路。

Analysis of brittleness of falling accident based on analytic hierarchy process

Falling accidents occupy the first place of the five injuries in high risk construction industry. By taking the falling accidents as the research object, we obtained the relative importance degree order vector of various factors lead to accidents with the method of Analytic Hierarchy Process（AHP）. According to brittleness theory of complex system and defining the brittleness awaken degree, we made a brittleness analysis on falling accidents. The results show that using unsafe facilities, no-protection measures, low strength and standing unsafe position are main brittle sources which lead to falling accidents. The research results provide a new way for establishing construction accidents prevention and control system.
