本文在确定了厂房区的初始应力场和边界条件的基础上，应用ADINA自动动态增量非线性有限元程序对思林水电站地下洞室群建立了平面弹塑性有限元计算模型。

This paper has got the initial stress field and boundary conditions . On this basis , the overall planar elastic-plastic finite element model of the underground caverns was established by ADINA ( a finite element program for automatic dynamic incremental nonlinear analysis ) .

通过介绍元磨及思小高速公路隧道施工过程中的工艺控制，就双连拱隧道的结构特点、中导洞及三导洞开挖方法、衬砌施工、特殊问题的处理等内容，提出了看法及建议。

Taking the double-arched tunnels on Yuan-Mo highway and Si-Xiao highway as example , the article expatiates on the structural features , central drift excavation method , three-drift excavation method , lining construction and some special issues of double-arched tunnels .
