摘 要:为了准确、迅速地判断爆破地震动作用下爆破工程的安全问题,便于更好地控制由于爆破地震动引起的危害效应,采用定性与定量相结合的形式,将层次分析法和模糊数学方法结合起来,根据最大隶属度原理,分析爆破地震效应的影响因素。研究结果表明:采用爆破地震效应影响因素评价指标体系、模糊评判分析模型及安全评估软件系统,能迅速、准确地判断爆破方案导致的爆破地震效应对周围环境的影响,其危险影响比较小,计算结果与实际工程爆破所得结果一致。本方法与实验分析方法相比,其原理简单、结果可靠,计算迅捷、节省时间、可快速应用于爆破实际工程中,同时又节省大量的费用。In order to accurately and rapidly judge the safety problems and control the harmful effects of blasting ground motion,the influence factors of the blasting seismic effect were analyzed according to the maximum membership degree principle.During the process of this research,AHP and fuzzy mathematics were combined qualitatively and quantitatively.The results show that the evaluation index system,fuzzy evaluation analysis model and safety evaluation software system can be used to quickly and accurately judge the impact of blasting seismic effect on the surrounding environment.The risk impact is relatively small,and the calculation results are consistent with the actual engineering blasting results.Compared with the experiment analysis method,this method has the advantages of simple principle,reliable result,fast calculation,time saving,rapid application in blasting engineering and large cost saving.
