| Abstract: | The comparison between the deformation property of plain concrete and steel reinforced concrete as well as steel fiber reinforced concrete tunnel lining was studied.Restricting crack open function of steel fiber after crack occurs was considered.The model tests of ring-shaped structure were conducted.The results prove that steel fiber concrete is more fit for the tunnel lining than the plain concrete.Modeling of collapse and analytical method of bearing capacity was put forward taking account of tension-softening relationship of SFRC.The results are helpful for the design of steel fiber reinforced concrete lining. |

| Keywords: | steel fiber reinforced concrete tunnel lining tension softening collapse behavior bearing capacity |
