岭南高速公路隧道二次衬砌结构有限元分析

The Finite Element Analysis of Tunnel Secondary Lining Structural of Lingnan Freeway

结合河南岭南高速公路隧道工程,建立隧道衬砌结构二维、三维模型,分析了隧道建成后衬砌结构的受力状态,并对结果进行比较分析,得到了一些有益的结论,验算了隧道衬砌结构的安全性。

Building two and three dimensional model of tunnel lining, the paper analysis the stress status of the lining structure been built and it analysis and compare the results, combining with the tunnel engineering of Lingnan freeway. It brings forward some worthy conclusions and shows that the tunnel is safety.
