摘要
采用ADINA有限元软件,应用弹塑性理论对某高速路双连拱隧道进行了有限元模拟,并对其稳定性进行分析,探讨了不同围岩应力释放程度对衬砌应力的影响,得出一些有益的结论,为双连拱隧道的设计和施工提供科学依据及技术指导。
By the FEM software ADINA and elast-plasticity therory,linking to practice of a highway double-arc tunnel,a FEM simulation was conducted and its stability was analyzed.The effect which is resulted from the different degree of the unloading progress of the surrounding rock on the stress of the support is discussed too.The paper provides good reference for design and construction of highway double-arc tunnels.
