摘要: 基于有限元分析了不同厚度下衬砌结构的受力特征,通过对比总结了衬砌结构安全系数随厚度的变化规律,得到了连拱衬砌厚度的合理取值。分析结果可以为连拱隧道衬砌工程设计提供参考。

Abstract: The stress distributions in the multiarch tunnels with various lining thickness were analyzed through the finite element method. The factor of safety of the lining structure correspondent to the lining thickness is obtained from the analyses so that the appropriate lining thickness can be selected. These results can be used in the design the similar lining structures for the multiarch tunnels.

Key words: multi-arch tunnels, lining thickness, safety factor
