| 摘 要： | 曲线箱梁桥受力比较复杂，设计中常采用设置横隔板的方法来减小截面变形和应力。通过计算分析，得出如下结论：一般情况下，曲线箱梁跨中只设一道横隔梁即能满足受力要求；对于大曲率、小跨径、腹板较厚的曲线箱梁桥跨中可不设横隔梁，支点横隔梁也可适当减小厚度。

| Abstract: | In the design of curve box
beam bridge,transverse isolated plate method is often used to reduce the deformation of
cross section and the stress.In this paper,through numerical computing and analysis,it is
concluded that in general cases,one transverse isolated plate is enough for loading,but for
curve box beam span with big curvature,small span and thick web,it is not necessary to use the
transverse isolated plate,and the thickness of transverse stiffened plate at supporting point
can be decreased to a certain extent. |
