| Abstract: | The counter-pressure filling with anti-slide piles,as an anti-unsymmetrical pressure measure,was used in a soft surrounding rock and unsymmetrical pressure tunnel.But the slip crack of tunnel heading slope and the deformation failure of supporting structure were caused by cave collapse during the tunnel construction.The failure reasons of counter-pressure filling with anti-slide piles were analyzed in this paper and the corresponding treatment measures were applied in combination with on-site practice condi... |
