爆破地震波作用于房屋结构体所产生的连续拉扭及超载作用将造成房屋墙面抹灰脱落、结构体裂缝开裂延伸等现象。在各振动物理量中 ,振动速度中的径向振动分量持续时间长、主频低且接近于房屋结构体自振频率 ,且楼体高层处径向振动速度分量相对于低楼层的有明显放大 ,放大系数β=1 .5 ,经分析认为爆破地震波中的径向速度分量在结构物破坏中是一个主要的因素。通过长期的爆破震动时结构物振动响应数据采集分析及结构体裂缝现象观测 ,提出了适宜某场区实际特征的普通民房结构体的容许振动速度标准v=2 cm/s Blasting seismic waves acting on the structure of the building continuous pull and overload caused by the role of housing walls will cause plaster off, cracks and other cracks in the structure of the phenomenon. In each physical quantity of vibration, the radial vibration component in the vibration velocity has a long duration, low frequency and close to the natural frequency of the building structure, and the radial vibration velocity component at the upper level of the building body is greatly magnified relative to the lower floor, Magnification coefficient β = 1.5, the analysis shows that the radial velocity component in the blasting seismic wave is a major factor in the structural damage. According to the data acquisition and analysis of the structure vibration response and the observation of the cracks in the structure during the long-term blasting vibration, the allowable vibration velocity standard for ordinary residential structures suitable for the actual characteristics of a field is proposed as v = 2 cm / s
