改进AHP-模糊综合评价在工程爆破安全评价中的应用

Application of improved AHP-fuzzy comprehensive evaluation in safety evaluation of engineering blasting

爆破是高危行业,安全问题引起了人们广泛的关注。针对工程爆破的安全问题,将改进AHP-模糊综合评价法应用在工程爆破安全评价中。以贵安新区某土石方爆破为例,从爆区环境、爆破参数设计、施工质量、安全管理四个方面构建多层次评价指标体系,运用三标度法构建判断矩阵,计算权重向量,进行模糊综合评价。结果表明,评价系统总分为78.85,该工程的安全状况为较好。该工程实例验证了改进AHP-模糊综合评价法的可行性,为爆破作业提供一定的指导作用。

Blasting is a high-risk industry,and the safety problem has aroused widespread concern.In view of the safety problem of engineering blasting,the improved AHP fuzzy comprehensive evaluation method is applied to the safety evaluation of engineering blasting.Taking the ordinary blasting of a certain earth and stone square in Guiyang as an example,the multi level evaluation index system is constructed from four aspects of blasting area environment,blasting parameters design,construction quality and safety management.Three scale method is used to construct judgement matrix,and weight vector is calculated and fuzzy comprehensive evaluation is carried out.The results show that the total score of the evaluation system is 78.85,and the safety condition of the project is good.The engineering example proves the feasibility of the improved AHP fuzzy comprehensive evaluation method,and provides some guidance for blasting operation.
