The strengthening effects of reinforced concrete liner cover for tunnel lining with crackles are investigated
and the numerical simulations for two computations of Tieshan Tunnel and Dayakou Tunnel are carried out by using a 2D FEM code. The computation results show that the stress intensity factors at the crackle tips can be decreased greatly; and the bearing safety factors of the linings can be raised obviously.
