| 摘 要： | 采用面向对象的编程技术，选取可视化的开发工具Visual Basic和Fortran Power Station编制了二维弹塑性有限元分析程序EPFEM-2D。以韩家岭大跨度公路隧道为例，通过地质勘察和实验室岩石力学物理实验确定了隧道围岩的类别及一些必要的物理力学参数，优选出了能较好反映隧道实际受力状况的计算模型，利用EPFEM-2D对韩家岭大跨度公路隧道的开挖过程进行了数值模拟，所得计算结果和有关结论为韩家岭大跨度公路隧道的设计及施工提供了重要的参考依据。

| Abstract: | Adapting OOP-object oriented programming techniques and choosing the visual software developing tools, such as Visual Basic and Fortran Power Station, work out the two-dimensional elastic-plastic finite element analyzing program EPFEM-2D. Taking Hanjialing large span road tunnel as an example, through geologic reconnoitering and the physics experiment of rock mechanics in the laboratory determine the classification of the tunnel and some essential physics and mechanics parameters, elect excellently the better calculation model that can reflect the actual received stress state in the tunnel, and utilize the self-programmed EPFEM-2D to simulate the excavation process of Hanjialing large span road tunnel. The results of calculation and relevant conclusion offer the important reference basis for design and construction of Hanjialing large span road tunnel. |
