摘要
应用有限单元法,讨论了设置双连拱结构所要求的两洞间距上限值;并研究了不同围岩情况下双连拱隧道的力学特性,得出了一些对工程设计有用的结论。
The higher limit of distance between double - arch tunnels required for placing the double - arch tunnel structure was discussed in detail with finite element method, with study of mechanical properties of the double - arch tunnel at the different surrounding rock, it indicates a useful conclusion for project design.
