【摘要】 通过现场监测，研究了低频爆破振动对距离爆源较远的高层与多层建筑物的影响。监测数据显示，爆破振动主频普遍低于10 Hz，易与建筑自振频率耦合。对于水平振动速度，多层建筑高层通常大于低层，而高层建筑则以中间楼层响应最明显；垂直振动速度则随楼层增高而增大。此外，中间楼层的振动位移显著大于其他楼层。研究结果表明，建筑结构对爆破低频振动的响应具有楼层差异性，需在爆破安全设计与振动控制中予以针对性考虑。更多还原

【Abstract】 Through on-site monitoring, this study investigated the effects of low-frequency blasting vibrations on high-rise and multistory buildings located at a distance from the blast source. Monitoring data revealed that the dominant frequencies of blasting vibrations generally remain below 10 Hz, which readily couple with the natural vibration frequencies of structures. Regarding horizontal vibration velocity, multi-story buildings typically exhibit higher values in upper floors compared to lower floors, with the most pronounced response observed in intermediate floors of high-rise buildings. Vertical vibration velocity increases with floor height, while vibration displacement in intermediate floors significantly exceeds that in other floors. The findings demonstrate that building structures respond to blast-induced low-frequency vibrations with floor-specific variations, necessitating targeted considerations in both blasting safety design and vibration control measures.更多还原
