摘　　要：针对爆破振动危害效应的影响因素众多,且各因素之间的综合作用具有不确定性的特点,基于云模型理论,建立了爆破振动对建筑物影响度的云模型评估模型。选取峰值振速、主振频率、持续时间、建筑物结构类型、建筑物新旧程度、场地条件6个主要影响因素作为评估指标,计算各指标隶属于不同爆破振动影响程度等级的云模型数字特征,结合正向正态云模型和指标权重,计算待评估对象的综合确定度,最后确定爆破振动影响度等级,将该方法应用于贵州省花安高速某边坡爆破振动对周边民房的影响度评估中。研究结果表明:云模型评估结果与模糊可拓分析法的评估结果较一致,且符合爆后实际调查情况,为合理评估爆破振动危害影响提供了一种新思路。Many factors make influence on the hazard effect of blasting vibration with the characteristics of uncertainty. Based on the cloud model theory,a cloud model evaluation model of blasting vibration impact on buildings is established. Six parameters are selected as main influencing factors as the evaluation indicators,including peak vibration velocity,main vibration frequency,duration,building structure type,building age and site conditions. The cloud model＇s numerical characteristics of each index belonging to different blasting vibration impact degree levels are calculated. Combined the positive normal cloud model with index weights,the comprehensive certainty of the object is calculated,and the blasting vibration impact grade is finally determined. This method is applied to the evaluation of the impact of blasting vibration on the surrounding residential houses on a slope of Hua＇ an Expressway in Guizhou Province. The evaluation results of cloud model are consistent with the evaluation results of fuzzy extension analysis method and the actual investigation after blasting.
