混凝土建筑拆除时振动衰减规律的试验研究

Experimental research on vibration decay law in concrete building demolition

对某混凝土建筑拆除过程中土体振动的速度、加速度进行实时监测,结果表明,楼房拆除产生的振动不大,低于振动预估值;振动波随着传播距离的增加,振动势衰减十分明显。

Soil vibration speed and acceleration are timely monitored in a concrete building demolition.Results show that the building demolition vibration is lower than vibration predicting value,and the vibrating wave increases with propagation distance,and vibration decay law is rather obvious.
