摘要
以某单洞单隔板双层地铁隧道为研究对象建立了有限元模型,分析了单洞单隔板双层隧道在不同阻尼比、不同动载作用下的应力和位移变化,通过分析比较得出有益结论,进而更深地了解了地铁荷载作用下不同阻尼比对隧道的动力影响。
Taking some single tube and one-seperator double floor subway tunnel as the research object, the paper establishes the finite element model, analyzes the stress and the displacement changes of the single tube and one-seperator double floor subway tunnel with various damping ra- tios and dynamic loading effect, concludes the beneficial results by comparison and analysis, and understands the dynamic influence of the various damping ratios on the tunnel under the loading effect of the subways.
