摘　　要：振动压路机引起的环境振动以波动的形式传播和衰减。根据波的吸收理论,分析了土壤媒质中振动波的衰减规律,按波能与振副的关系,推导了振幅随距离衰减的计算公式,结合环境振动测试结果及建筑物地面振动容许限值,给出了振动压路机的安全工作距离及隔振沟障等危害预防措施。结果表明,振动压路机引起的环境振动以柱面波形式传播并随地面距离平方根的倒数的规律衰减。According to the energy theory of the cylindrical wave, the attenuate rule wave in soil was analyzed. Based oa the relationship between wave energy and amplitude, the formulas about its calculation was given. Combining the testing results with the tolerance limit of the ground vibration, the safe space and some steps of damage prevention was discussed. The results show that the vibration propagates in environment as cylindrical wave, its strength decreases with the quare root's reciprocal of distance.
