摘　　要：本文把斜交地道桥简化为板梁组合结构,实现了墙角处的位移协调。数值算例表明,这种方法是适用和可行的。In this paper, the analysis of oblique framed tunnel bridge is simplified as a plate and beam composite structure, and the displacement compatibility condition at a corner of the wall is satisfied. Numerical results reveal the method is practical and available.

关 键 词：斜交地道桥 板梁组合结构 等参数单元 刚度矩阵
