基于十堰市高家沟堰口采石场爆破开挖工程现场试验，对矿山附近一栋多层建筑物进行爆破振动监测，分析了该建筑物不同楼层的振动速度及谐波频率的变化规律。结果表明：爆破远区的多层建筑物受爆破振动影响时，垂直方向振动速度随着楼层高度的增加而变大，水平方向振动速度随着楼层高度的增加而变小；爆破振动产生的谐波频率丰富，较高楼层谐波频率分布范围小于较低楼层且更接近建筑物的固有频率。

Based on the blasting excavation case in Yankou Quarry ,Shiyan city ,the blasting vibration of a multi‐storey building near the mine was monitored ,and the variation of vibration velocity and har‐monic frequency on different floors of the building were analyzed .The results show that when the multi‐storey building far from the blasting source has been affected by the blasting vibration ,the vi‐bration velocity in the vertical direction increases with the floor height while that in the horizontal di‐rection decreases with the floor height .The harmonic frequency induced by the blating vibration is a‐bundant ,its distribution range on higher floor is smaller than that on lower floor ,and the harmonic frequency on higher floor is closer to the inherent frequency of the building .
