| 摘 要： | 为研究建筑物爆破拆除过程中产生的振动效应,对一高层框架结构建筑物爆破拆除过程进行振动监测,并对爆破振动与塌落振动数据进行对比分析。研究发现,爆破振动峰值速度的衰减速率大于塌落振动峰值速度;塌落振动信号优势频带能量大于爆破振动信号;塌落振动信号的频率接近建筑物的自振频率,危害性更大。

| Abstract: | In order to study the effects of vibration generated during blasting demolition,the vibration of the demolition of a high frame structure building was monitored,and the blasting and collapse vibration were compared and analyzed.The results showed that the attenuation of peak velocity of blasting vibration was faster than the collapse vibration's.The energy of advantage frequency band of collapse vibration signals were bigger than the blasting vibration s.The frequency of collapse vibration was closer to natural frequency of the building,and its hazard was greater than the blasting vibration's. |
