摘要
依据BW219DH-3型振动压路机的地面振动监测数据,对其地面振动传播的衰减规律进行了统计分析,结果表明振动压路机引起的地面振动Z向加速度的传播规律符合负幂函数形式a=αR-β。并结合相关标准对其引起的环境振动影响进行了评价,确定了高频(28.12Hz)时环保距离为237m,低频(22.27Hz)时为56m。
According to the experimental data of vibration roller, it is reasonable that the attenuation of vibration acceleration can be described by negative power function. Vibration effect on human body which is based on vibration criteria of urban regional environment is introduced and the safety distance is 237 m, 56 m, for frequency of 28.12 Hz, 22.27 Hz, respectively. Some conclusions could be used as reference in the road construction of pavement.
