摘要
本文通过对带接缝多板系统和地基的耦合分析来研究隧道刚性路面板的性能 ,研究中把地基假定为文克勒地基 ,路面板间的接缝假定为剪切弹簧单元 ,并用压缩矩阵简化法解算多板系统。编制了有限元分析程序 ,此程序可得到隧道路面板的荷载 弯沉曲线 ,结合无破损弯沉检测法可判断隧道路面性能。
In this paper, the performance of rigid pavement of the tunnel is studied by couple analysis of multi-slab system with joint and the foundation. It is assumed that the foundation is Winkler one and the joints are shear spring elements; the multi-slab system is calculated by compressed matrix. The load-flexure curve of the tunnel pavement can be obtained by FEA program, which can judge the tunnel pavement performance in corporation with nondestructive test method by deflector.
