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。

Taking the shield structure tunnel beneath rail line as the background ,we used finite ele‐ment program to establish a numerical simulation by the method of stratigraphic structure after con‐sidering the dynamic load caused by the train above the tunnel .We analyzed synthetically the relation‐ship between railway train dynamic stress and segment internal forces in the phase of tunnel construc‐tion and operation .
