摘　　要：本文利用板梁有限元模型,对斜交箱形地道桥在不同斜交角度下的扭矩分布作了讨论。数值结果表明,斜交桥设计中应充分考虑扭矩作用。This Paper discusses the distribution of torsional moment for the tunnel bridge in various oblique angles, by using finit element model of plate and beam. Numerical studies revealing the design of oblique tunnel bridges should full considered the action of torsion.
