摘要
隧道衬砌开裂将影响隧道的承载能力和使用安全。文章主要分析了铁路隧道开裂状况及原因 ,对裂缝宽度的影响程度进行了分级 ,利用断裂力学的方法研究了衬砌开裂隧道的稳定性 。
Lining cracks will affect the bearing capacity and the safety of tunnels. In this paper, cracks on linings and the causes for their occurrence in railway tunnels are analyzed, the degrees of influence of different crack widths are classified with the stability of the tunnels with cracked linings studied by the method of fracture mechanics. Finally, the techniques for repairing the cracks are proposed.
