摘　　要：针对台阶爆破效果综合评价方案中各项指标的未确知性,应用信息熵理论及层次分析法结合模糊物元理论,建立台阶爆破优选的AHP-熵模糊物元综合评价模型,并选取大块率等12项影响因素作为对应的模糊量值组成复合模糊物元指标。根据各指标调查统计值,通过层次分析法与熵权法分别确定各指标主观与客观权重,以最大关联度为评判标准优选出最优方案。利用洪水台土石方平场项目4次台阶爆破效果对该模型进行验证与计算,采用Maltab软件编程计算其主客观权重与最大关联度,得出4次台阶爆破效果的最大关联度分别为0.8830、0.8836、0.8111、0.8608,从而确定最优台阶爆破方案。To deal with the uncertainty of the indicators in the comprehensive evaluation scheme for bench blasting effect,the application of fuzzy matter-element theory combined with analytic hierarchy process and information entropy theory was used to establish the AHP and entropy fuzzy matter-element comprehensive evaluation model,and the rate of blasting chunk was selected as the 12 factors such as bench blasting effect comprehensive evaluation index.According to each index survey statistics,the subjective and objective weights of each index were determined by AHP and entropy weight method respectively.The model was validated and calculated by using the 4-step blasting effect in Hongshuitai field-leveling project,and the subjective and objective weights were calculated by a Maltab software programming and maximum correlation,the maximum correlation degree of 4-step blasting effect were 0.8830,0.8836,0.8111,0.8608.Finally,the optimized blasting scheme was obtained.
