摘　　要：民房附近进行工程爆破时,爆破地震波对民房具有破坏作用。作用于房屋的爆破水平地震力易使砖砌房屋受剪力产生破坏。应用反应谱理论,得到了爆破水平地震力和房屋剪力的计算式。通过对民房破坏进行分析和观察,介绍了民房的爆破地震破坏特征。When blasting engineering is performed near by residential houses, blasting vibration wave has an effect of damage on the residential houses. The residential houses are damaged owing to effect of shearing force effect to the houses. According to the theory of reaction spectrum, equations of seismic force and shearing force are obtained. Damage characteristics of blasting vibration for residential houses are introduced by analysis and observation of damage for the residential houses.
