| Abstract: | Earthquake response of tunnel portal section is analyzed with the dynamics function of large-scale general finite element software ANSYS.The maximum stress and displacement curve of lining wall feet along tunnel axial line under each condition are obtained.Through analysis,the earthquake-proof defense length of tunnel portal section under each condition is determined,which provides reference for similar engineering. |
