| 摘 要： | 随着近年来国内城市地铁建设、运营的快速发展，地铁运行产生的振动对周边地上及地下环境的影响应得到重视。以某一计划建于地铁隧道上方的地下商城为研究对象，采用数值模拟的方法研究地铁运营中产生的振动对该地下商城施工安全的影响。得出以下结论： 1）地铁振动对地下商城各步开挖的关键部位的应力和变形有一定的影响； 2）这种由地铁运行诱发的振动对商城施工安全无严重威胁。

| Abstract: | With the development and operation of Metro systems in China, attentions should be paid to the influence of the vibrations induced by Metro trains on the surrounding environment. The influence of the vibrations induced by Metro trains on the construction of an underground shopping mall located above the Metro tunnel is analyzed by means of numerical simulation. Conclusions drawn are as follows: 1) The vibration induced by Metro trains has some influence on the stress and deformation at key points during the excavation of the underground shopping mall. 2) The influence of the vibration induced by Metro trains on the construction of the underground shopping mall is minor. |
