摘　　要：针对静态膨胀剂膨胀生裂施工过程中容易发生喷孔伤人事故,运用事故树定性分析方法分析静态膨胀剂喷孔伤人事故的基本原因,建立静态膨胀剂喷孔伤人事故树,利用布尔代数化简法求解出135个最小割集和3个最小径集,通过结构重要度分析确定了各基本事件的重要程度并进行排序,并从加强安全防护、防止人员处在危险区和防止静态膨胀喷孔3方面提出具体措施。This paper use the method of fault tree analysis to analyze the basic reason of static expansion agent jetting orifice and leading to injury accident, established accident tree of static expansion agent jetting orifice and leading to injury accident, using the method of Boolean algebra reduction to figure out the 135 minimal cut sets and 3 minimal path sets, established the importance of each basic event through the analysis of structure importance degree and sequencing based it, putting forward to the effective and specific measures to prevent the accidents of static expansion agent wounding accident duing to jetting orifice from following three aspects： strengthening safety protection, preventing people occurring dangerous areas and preventing static expansion jetting orifice.
