| 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,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.量纲分析法证明,上述统计衰减规律也是符合物理规律的.这就为正确评价压路机在相同土质条件和工作状况下振动作业时对附近建筑物的影响提供了科学依据.

| Abstract: | According to the experimental date of ground vibration produced by vibration road roller,the atten- uation of vibration acceleration is statistically analyzed and the result indicates that to describe the attenuation of vibration acceleration by negative power function is reasonable.It is verified by dimensional analysis that the above mentioned statistical attenuation is also in conformity with physical law.The paper provides scientific basis for correctly evaluating the effect on nearby building of ground vibration caused by road roller in same site soil and working condition. |
