实测爆破、打桩振动与地震动的反应谱比较分析

摘要

According to the ground motion time-history curve of blasting and piling, response spectrum of blasting and piling and seismic are respectively calculated based on response spectrum theory, the influence law of the blasting and piling vibration is obtained by comparative analysis with earthquake response spectrum curves.%采用反应谱理论,根据实测的爆破施工及打桩振动地面运动时程曲线,对自然地震、爆破及打桩施工振动的反应谱分别计算,通过与自然地震反应谱曲线的比较分析,获得了爆破及打桩振动相对于自然地震所不同的影响规律.
