摘　　要：为探究振动在地面及建筑物内传递规律,在北京交通大学芳华园中利用建筑物模型进行了现场测试。利用力锤敲击产生的激励力所产生的振动,对整个系统进行了振动响应分析,通过计算在地面及建筑物上的传递比,讨论振动在地面及建筑物中传播的总体规律。该结果对如何减轻交通引起的建筑物振动具有一定实际意义。In order to explore the transmission law of vibration on the ground and in buildings,this paper conducted a field test using a building model in the Fanghua Garden of Beijing Jiaotong University.The vibration response analysis of the entire system is made by using the vibration generated by the excitation force generated by the hammer.The overall law of vibration propagation on the ground and buildings is discussed by calculating the transmission ratio on the ground a nd buildings.This result has practical significance for how to reduce the vibration of buildings caused by traffic.

关 键 词：振动 激励 传递比 传递规律
