Abstract

Taking lining structure crack diseases on one line of Beijing subway as the research object, using indoor model test method to studying lining structure damage rule and crack maintenance effect. Through experiment, it was concluded the main conclusions as follows: Through the contrast test could be obtained that, the yield load of crack grouting reinforcement test beams could increased by 6% ~ 8%, the ultimate load of test beams could increased by 4%. The main purpose of crack grouting reinforcement technology was to restore structure overall stress form, and the bearing capacity of experimental beams increase is not obvious. The research conclusions have important theoretical guiding significance for the comprehensive treatment work on the tunnel lining structure cracks ,which during the next phase.
