摘要
为了对爆破振动影响程度进行合理的评估,将模糊数学与可拓学方法相结合,在物元理论、可拓集合论和关联函数的基础上,利用爆破振动影响度等级分类和评估指标隶属度化值,构造了经典物元和节域物元,结合模糊层次分析法确定评估指标的权重,建立了爆破振动影响度的模糊可拓评估模型。将建立的模型用于某边坡爆破开挖工程的振动影响度评估中,给出7个评估对象的影响度等级,通过爆后实地调研证明该评估结果较符合实际情况,可为爆破方案的改进以及合理有效地控制爆破振动提供决策依据。
In order to evaluate the influence extent of blasting vibration,this paper combines the fuzzy mathematics with the extension method.Based on matter element theory,extension set theory and correlation function,the influence degree of blasting vibration classification and evaluation index membership value are used to build the classical matter element and the joint element.Fuzzy analytic hierarchy process is used to determine the weight of evaluation index,and the fuzzy extension evaluation model of blasting vibration effect is established.The model is used to assess the degree of influence of vibration of a Slope Blasting Excavation Engineering,providing 7influence grades of evaluation object.After blasting,the results show that the evaluation results are in line with the actual situation,which can provide decision-making basis for the improvement of blasting scheme and the reasonable and effective control of blasting vibration.
