摘要
采用GeoFBA有限元软件,应用弹塑性理论,对沈大高速公路韩家岭大跨度隧道进行了有限元模拟,并对其稳定性进行分析,以保证隧道运行安全经济合理.所得计算结果和有关结论同时填补了我国在大跨度公路隧道分析方面的空白,为隧道的设计及施工提供重要的参考依据.
By the GeoFBA- 2D and elast-plasticity theory, linking to practice of Hanjialing large span road tunnel of the Shenyang-Dalan motorway, a FEM simulation was conducted and its stability was analyzed. By these analysis, safety during the time of the tunnel operating will be ensured. At the same time, the calculation results and relevant conclusion can make up blankness of analysis on large span tunnel, and offer the important reference basis for design and construction of tunnel.
