摘要:

为了评估从北京西站到北京站地下直径线建成运营后列车振动对北京地铁2号线隧道结构产生的影响,结合工程实际,从理论上分析了在列车运行引起的随机振动作用下,地下隧道钢筋混凝土结构产生疲劳破坏的机理,综合考虑了地下环境对地铁隧道结构产生的影响,并参照国内外相关控制标准,得到在地下直径线正常运营情况下,北京地铁2号线隧道结构安全及正常使用的振动控制标准。

Abstract:

In order to assess the effects on the tunnel structures of metro line 2 due to the vibrations induced by the underground trains on the Diameter line which connects two of the biggest railway station in Beijing, a standard of vibration assessment is presented in this paper. The standard is based on the theory of the fatigue damage in the concrete structure due to the application of vibrations. Moreover, the influence of the underground environment on the tunnel structures is also considered, and some standards of vibration assessment in China and other countries are referred in this standard.

Key words: tunnel  , vibration  , standard  , fatigue damage
