以东莞虎门镇威远岛环岛路炮台及兵营遗址为研究对象，建立工程公路-山体-兵营整体三维数值分析模型。采用有限元程序进行动力时程分析，计算炮台、兵营在不同车辆轴重、行驶速度的振动响应，获得加速度、速度沿距离分布规律，分析各因素对遗址振动影响。结果表明，车速由40 km/h增加到80 km/h时炮台底座速度响应增加4%~13%，而兵营地基速度响应增加6%~30%；轴重由15 t 增加到55 t 时炮台底座、兵营地基响应与轴重成正相关增大。通过在震源处施加竖向变频率简谐作用力进行谐响应分析知模型卓越频率分别在10 Hz及40 Hz附近；外部交通振动荷载频率近10 Hz时，炮台底座、兵营地基振动响应最大。

Selecting the old barracks and the fort relics, which are situated at Humen, Dongguan, as the research object, the whole 3D model was established for numerical simulation. In order to calculate the structural vibration response caused by the different vehicle speed, the axle weight, the time-historical analysis was completed by using finite element method. The vibration acceleration and velocity was investigated and the effect of moving vehicle load on the relics was analyzed. The results show that if the vehicle speed increases from 40km/h to 80 km/h, the velocity response of the fort base has increased by 4%-13%; also that of the foundation of barracks has increased by 6%-30%. Similarly, if the axle load increases from 15t to 55t, the response of the relics base appears positive correlation with the increasing of the axle weight. By changing the frequency of the vertical harmonic force, the harmonic response analysis was finished. It was shown that the predominant frequencies of the model were close to 10Hz and 40Hz. When the loading frequency was about 10Hz, vibration response of the foundation of the old barracks and the fort reached the maximum value.
