| 摘 要： | 针对直墙拱双层隧道衬砌结构,对中隔板与边墙的相互作用进行了理论分析,建立了中隔板与边墙相互作用的力学模型。采用数值分析软件Matlab按弹性地基梁理论对中隔板在边墙上的位置进行了模拟,得出了中隔板对边墙位移约束的力学机理,最终得到了中隔板在边墙上的最佳作用位置。

| Abstract: | For vertical wall double-deck tunnel lining structure,a theoretical analysis is carried out and the mechanical model is set up for the interaction between baffle plate and vertical wall.By using numerical analysis software Matlab,according to the theory of elastic foundation beam,a simulation about the baffle plate location on the vertical wall is conducted.The mechanical mechanism of the baffle plate in restricting the displacement of the vertical wall is clarified.Finally,the optimal baffle plate location... |
