　　为研究地铁振动对地面建筑物的影响，建立隧道—土层—地面建筑物系统的三维结构有限元模型进行数值计算，得出地铁隧道与地面建筑物的水平距离、隧道埋深以及建筑物桩基不同深度对振动传递的影响，并将数值计算结果与实测结果做了对比分析。结果表明，增加隧道埋深和增大隧道与建筑物水平距离都能减小建筑物振动，建筑物桩基使地铁振动能量传递损失减小，不利于建筑物减振；三维有限元模拟数值计算结果与实际情况相符，对于工程设计实践具有一定的参考价值。

A three dimensional FEA model of tunnel-soil-building system was established to investigate the effects of subway vibration on ground building. The impacts of the horizontal distance from subway tunnel to ground building and the depth of the building piles on vibration transmission were calculated and analyzed. The numerical results were compared with the measurement data. The results show that increasing of tunnel depth or horizontal distance from subway tunnel to building can reduce the vibration of the building, but building piles can reduce the transmission loss of subway vibration energy, and are unfavorable for vibration reduction of the building. The results of simulation by three dimensional FEA model are consistent with the data from practical engineering. This study is of significance for reference in engineering design.
