Influence of Tunnel Lining Thickness on Structural Safety and Evolution Laws of Crack

  • Against the background of a expressway tunnel project in Guangxi, a 3D numerical model was constructed by the finite element analysis software ABAQUS to simulate and study the influence of insufficient lining thickness on the safety of lining structures and crack propagation laws. The results indicated that the insufficient thickness of tunnel linings would significantly affect the safety of lining structures, and the safety factors at thickness reduction positions decreased with the decrease of the thickness. The insufficient thickness at the vault had a greatest impact on the safety of lining structures, the dispersive distribution of the lining thinning had a greater impact on the safety of the vault and arch shoulders, and the concentrated distribution of the lining thinning had a greater impact on the safety of side walls. Crack first appeared in the inside of linings corresponding to the lining thinning area. With the decrease of lining thickness, the number of cracks increased, the cracking speed increased, and destruction advanced simultaneously. The cracking area generated by the concentrated distribution of lining thinning was larger than that by the dispersed distribution.
