摘要
Abstract
In the construction of tunnels and underground structures, there is more and more tunnel collapse because of the complicated geometrical and topographical conditions. Due to the unpredictability of the collapse, seriousness of the results and complication of the treatment, the collapse is a very difficult problem in the tunnel construction. The long pipe roof is a longitudinal support using steel pipes or sheets. As this structure has great rigidity and long span, it is an effective form to treat the tunnel collapse. In this paper, the mechanical model of the long pipe roof to treat the tunnel collapse is studied. A simple and effective mechanical model is proposed. The relative parameters have been calculated. Using this model, the treatment of Sigou Tunnel of Shibai Express has been analyzed. The example shows that the proposed model is reasonable and valid and the rationality of the treatment scheme has been proved by the numerical simulation, monitoring and measuring data.关键词
