Abstract: The authors analyze the stress intensity factors at the tips of cracks in a tunnel lining and the safety factors for bearing capacity of the tunnel lining by using a 2D FEM code, in which the influences of lengths, widths and number of cracks are mainly considered. The computation results show that the stress intensity factors raise and the safety factors of bearing capacity decrease with the increase of lengths and number of cracks, but the effect of crack widths is not so obvious.

Key words: tunnel lining, crack, stress intensity factor, 2D finite element analysis
