振动压路机对建筑物的振动影响及控制对策

Vibration effects of vibratory roller on nearby buildings and its control measures

为了治理振动压路机施工时对建筑物的振动影响,对采取隔振措施前、后振动压路机诱发的振动进行了测试,对试验数据进行了回归分析,并对隔振前、后的地面振动数据进行了对比研究。结果表明:地面振动波传播衰减规律符合负幂指数函数形式,隔振沟隔振效果明显,最小安全施工距离隔振前为12 m,开挖隔振沟后为7 m。

In order to control the effects of ground vibration induced by vibratory roller on the structure along the road, the experimental data of vibration is presented, it is analyzed and compared with the vibration acceleration of insulation trench experiment. The results indicate that to describe the attenuation of vibration acceleration by negative power function is reasonable. It is found that the isolation trench is in good effect, the safe distance reduces from 12 m to 7 m. 3 tabs, 8 figs, 12 refs.
