中文摘要：
针对岩架大桥的爆破拆除方案,开展了周围民宅爆破震动的监测研究,并对获得的震动实测数据进行了相应分析。结果表明,地表拆除爆破地震波衰减较快,结构物应尽量采取3个方向同时监测;同一爆破,不同结构物测点三向震动速度值的大小变化趋势可能不一样,但对同一结构物,不同层的测点在三向数值上大小变化趋势一致,并存在一定的放大效应。
英文摘要：
According to the blasting demolition program of Yanjia bridge,the blasting vibration test of the civilian buildings around the bridge was carried out,and the obtained data of blasting vibration was analyzed.The results showed that the surface seismic wave incurred by the demolition blasting attenuated faster.The vibration of the structures should be measured in three directions at the same time.In the same blasting,for different structures the change trend of measured points vibration velocities in three d...
