| 摘 要： | 结合某联拱隧道现场监测，对洞周收敛和拱顶沉降的监测数据进行处理分析。通过分析拱顶收敛和洞周收敛的变化规律，探讨了隧道受力与二次衬砌施作最佳时机之间的关系；洞周位移黏弹性分析表明，在开挖46d后，围岩已趋于稳定，二次衬砌最终受力较小，可以进行二次衬砌作业。 |
| 关 键 词： | 联拱隧道 二次衬砌 稳定性 粘弹性 |

| Abstract: | The data from monitoring the convergence of the surrounding rock and the arch were analyzed based on the on-the-spot monitoring of a bi-arch tunnel.According to the variation law of the convergence lines,the relationship between the stress in tunnel and the best time of secondary lining was analyzed.The results show that the surrounding rock of the tunnel becomes stable after 46 days and the final stress of the secondary lining is small. |
| Keywords: | bi-arch tunnel secondary lining stability viscoelasticity |
