| 中文摘要: |
| 以盾构隧道下穿铁路为依据，考虑盾构推进时上部列车行进产生的荷载，采用地层结构法，利用有限元分析软件建立数值模型，综合分析了在施工开挖阶段和施工完成后运营阶段列车动应力和隧道管片内力之间的影响。 |
| 英文摘要: |
| Taking the shield structure tunnel beneath rail line as the background, we used finite element program to establish a numerical simulation by the method of stratigraphic structure after considering the dynamic load caused by the train above the tunnel. We analyzed synthetically the relationship between railway train dynamic stress and segment internal forces in the phase of tunnel construction and operation. |
