摘要: 为有效控制爆破危害因素,以连续多跨渡槽复杂结构拆除爆破为研究对象,利用模糊层次分析法(FAHP),构建渡槽拆除爆破安全评价模型;建立三角模糊函数以定量刻画比较强度,通过定义相应矩阵运算获得不同层级影响因素的权重及隶属度,分析获得安全评价对象的评价等级。研究表明:FAHP定量评估拆除爆破的安全风险,并获得影响因素的权重及其重要度排序;迎春渡槽安全评价综合得分为75.18分,评定为“较安全”等级;从而完成爆破设计参数优化,提高钻孔、断点位置、预处理等环节施工质量。

Abstract: In order to effectively control blasting hazard factors, with demolition blasting of continuous multi-span aqueduct's complex structure as research object, a safety evaluation model of its demolition blasting was established by using FAHP method. Then, a triangular fuzzy function was developed to quantitatively describe comparative strength. Finally, weight and membership degree of influencing factors at different levels were obtained by defining corresponding matrix operation, and safety evaluation grade of the object was analyzed. The results show that FAHP quantitatively evaluates safety risk of demolition blasting, and obtains weight and importance ranking of influencing factors. And comprehensive assessment score of the object is 75.18, rated as "relatively safe". Blasting design parameters are optimized, and construction quality of drilling, breakpoint location and pretreatment is improved.

Key words: fuzzy analytic hierarchy process(FAHP), continuous multi-span, aqueduct, demolition blasting, safety evaluation
