FTA-AHP法在爆破飞石事故原因分析中的综合应用

Comprehensive application of FTA-AHP method in the cause analysis of blasting flying stone accident

单独使用FTA或AHP分析方法进行爆破飞石事故分析时,均存在一定的不足。为进一步研究各基本事件对顶上事件的影响程度,采用FTA-AHP综合分析法对其进行分析。以某机场东围界外侧A、B、C三座山体爆破开挖为背景,根据现场调研结果编制爆破飞石事故树并进行结构重要度分析,以爆破飞石事为目标层,爆破设计及施工、地质条件、环境及安全管理为准则层、各基本事件为指标层,构造爆破飞石事故的FTA-AHP综合分析模型并进行权值计算。结果表明:事件X1至事件X7及事件X9对爆破飞石的影响权值最大,根据分析结果确定了预防重点,制定了相应的防预措施,从而有效防止了爆破飞石事故的发生。

There are some deficiencies in the analysis of blasting flying stone accidents by using FTA or AHP method alone.In order to further study the influence of the basic events on the top events,the FTA-AHP comprehensive analysis method was used to analyze them.At an airport east perimeter boundary A,B,C three mountain blasting excavation as the background,according to the field investigation results to prepare blasting flying stone accident tree and structural importance analysis,with blasting flying stone as the target layer,blasting design and construction,geological conditions,environment and safety management as the standard layer,the basic events as the indicator layer,The FTA-AHP comprehensive analysis model of blasting flying stone accident is constructed and the weights are calculated.The results show that the influence of incident X 1 to incident X 7 and incident X 9 on blasting flying stone is the most important,and based on the analysis results,the prevention emphases are determined and the corresponding preventive measures are established,which can be used for reference by peers.
