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 degree of blasting vibration reasonably, combining the fuzzy mathematics and extenics method, based on matter element theory, extension set theory and correlation function, the grade of blast vibration influence degree is used to classify and evaluate the index membership The value of classical and metamorphic objects is constructed. The fuzzy analytic hierarchy process (AHP) is used to determine the weight of the evaluation index. A fuzzy extension evaluation model of the influence degree of blasting vibration is established. The model is used in the vibration impact assessment of a slope blasting excavation project, and gives the impact rating of seven assessment objects. The results of field investigation after blasting prove that the assessment result is more realistic and can be used in blasting scheme Improve and reasonable and effective control of blasting vibration provide the basis for decision-making.
