| 摘 要： | 以文克尔弹性地基梁理论为基础,建立了隧洞衬砌静力分析的杆系结构力学模型,使其可考虑底部为弹性转动约束的情况,并对该模型进行了实例验证。研究结果表明,考虑弹性转动可使拱顶及边墙顶部截面受拉边缘处的应力增加。

| Abstract: | Based on Winkler's beam on elastic foundation,the system bar model of structural mechanism for tunnel lining static analysis was proposed,which can be applied in situation of elastic rotation ends at bottom of lining.The proposed model was also proved through the analysis and contrast with another method of one practical project.The result showed that the lining arch top and wall top stress was increased by considering the effect of elastic rotation restraint. |

| Keywords: | tunnel lining static analysis mechanical model elastic rotation |
