摘要
利用MIDAS-GTS有限元分析软件,对隧道出口浅埋段的施工进行了数值模拟,从位移、应力角度分析了围岩破坏的原因,并根据分析结果提出了围岩支护措施,从而为保证隧道顺利通过此段奠定了理论基础。
By using MIDAS-GTS finite elementary analysis software,the paper has the numerical simulation for the shallow section＇s construction of the tunnel＇s exits,analyzes the surrounding rock damages from the displacement and stress aspects,and points out the surrounding support measures according to the analysis results,so as to lay the foundation for ensuring the smooth tunnel construction.
