摘要
采用粘弹性方法对隧道施工过程中的力学动态进行了时间效应分析,探讨了二衬支护时间对围岩位移、初衬应力、二衬应力的影响,得出了Ⅴ级围岩隧道的二衬在开挖完60 d内施作较为合理的结论。
The time effect of mechanics dynamic in tunnel construction process was analyzed with viscoelasticity method,the secondary lining supporting time influences on rock displacement,first lining stress and secondary lining stress were discussed.It concluded that V grade rock tunnel secondary lining was rational after 60 d excavation.
