摘要
在文献［１］的基础上，用理论和数值方法定量地分析了超挖对圆形和马蹄形隧道的应力影响状态。研究表明，隧道超挖将引起围岩内的局部应力集中。
Based on the paper,by applying theoretical and numerical methods,the tunnel overbreak influence on the surrounding rock stress has been quantitatively analyzed.The results of research show that the tunnel overbreak will cause the local stress concentration in the circular section tunnel and the horseshoe shaped tunnel and will make serious influence on the stability of tunnel.
