| 摘 要： | 对隧道衬砌开裂的原因进行了综合分析,并利用ansys软件对衬砌在结构完整和出现裂缝的受力情况进行了对比。结果表明,裂缝给衬砌带来的应力变化比较显著,拱墙径向裂缝对衬砌力学性能影响很大,沿隧道纵深方向影响较小。

| Abstract: | The cause of tunnel lining cracking was analyzed comprehensively,and the stress condition of the lining under cracking and that of lining under structure integrity were compared by using ansys software.The result showed that the cracking brought significant change to lining,the influence of radial cracking of arch wall on the mechanical properties of lining is great,and the influence of longitudinal direction along the tunnel is small. |
