| 摘 要： | 根据BW219DH-3振动压路机施工时引起的地面振动监测资料,对其衰减规律进行了统计分析和量纲分析,表明可用负幂函数描述振动压路机引起的地面振动衰减规律。并对隔振沟的隔振效用进行了试验研究,隔振效果明显,安全隔振距离从隔振前的12m减少到7m。这就为正确评价振动压路机施工时地面振动对附近建筑物的影响及控制提供了科学依据。

| Abstract: | Following the monitoring data of ground vibration induced by a vibratory road roller, the paper carried out the statistical and dimensional analysis of its attenuation law, which can be described, as the analysis shows, by the negative power function. It also conducted an experimental study of the vibration-isolation effect of a vibration-isolation trench, proving that the effect is obvious. Its safe distance of vibration isolation is reduced from the 12 meters before vibration isolation to seven meters. The study provides a scientific ground for correctly evaluating the impact of the ground vibration induced by a vibratory road roller on nearby buildings. |
