摘要
文章以某山岭隧道为研究背景,采用数值试验的方法,分析了不同间距下的分离式隧道围岩塑性区分布范围、岩柱体应力状态以及围岩变形量的变化规律,以及不同间距对隧道围岩稳定性的影响,提出了分离式平行隧道合理间距的范围。
With a mountain tunnel as research background, by using the numerical experiment method, this article analyzed the distribution range of plastic zone,the stress state of rock column and the variation rules of surrounding rock deformation amount for the surrounding rock of separate tunnels under different spacing, as well as the impact of different spacing on the stability of tunnel surrounding rocks,and proposed the range for reasonable spacing of parallel separate tunnel.
