| Abstract: | The tunnel dug in permafrost area is in explore system, wall rock refreeze and crack water converte into ice. So freezing rock pressure formed behind lining makes the lining deformating and losting the stability. By the relastic theory, additional stresses produced by freezing rock pressure are primarily analysed, a equation of freezing rock pressure and the stability condition of lining are given. By calculating, effects of the tunnel wall rock refreezing on the lining stability are analysed. Some steps for protecting frost damage are discussed. |
