| 摘 要： | 结合沈大高速公路改扩建工程中韩家岭单洞四车道隧道工程实例，对超大跨隧道施工中各个阶段的力学行为进行了数值分析，判断围岩与支护衬砌结构在各个阶段的安全性与稳定性。通过与室内模型实验、现场监控量测的有关结论进行比较，验证了数值分析结论的正确性，从而判断超大跨隧道支护衬砌参数是否合理、施工开挖方法是否可行。实践证明，该隧道的支护衬砌参数与开挖方法是可行的，为类似隧道的设计与施工提供了借鉴。

| Abstract: | According to the project of Hanjialing tunnel with four lanes in the expressway rebuilt from Shenyang to Dalian,the mechanics action is discussed about the constriction phases by numerical analysis to estimate the security and stability of the rock,support and lining.The numerical analysis result was compared with that of model test and measure result to prove the correction of the numerical analysis,at the same time,the rationality of support parameters and feasibility of excavation were decided.It is proved that the support parameters and excavation method are feasible.It can be referred for the same tunnels in the future. |
