摘　　要：爆破地震是城市岩石地下工程施工的重要灾害之一，对其进行准确的预测十分重要。本文通过围岩分类因素对围岩类别及爆破地震传播影响的内在关系分析，在对城市地下工程现场围岩分类及爆破地震量测的基础上，首次建立了围岩类别与爆破地震之间的关系。The propagation of blasting sesmic wave is affected by the all factors of classification of surrounding rock. This paper analysed this problem. On the basis of classification of surrounding rock about urban underground projects and survey of blasting vibration, it is firstly founded that the quantitative relation between classification of surrounding rock and blasting vibration. The more feasible data are supplied for prediction of blasting vibration and blasting design.

关 键 词：爆破 地震 围岩类别 地震工程
