| 摘 要： | 在考虑钢筋混凝土箱梁整体变形的基础上，用空间有限元分析程序对箱梁顶板、翼缘板在轮胎荷载作用下的横向受力进行了系统的参数分析，通过回归分析得出箱梁在变截面参数下行车道板的横向弯矩与横向受力分布宽度经验计算公式，并将经验值与有限元值及我国现行桥梁规范值(JTJ023～85)进行了比较。

| Abstract: | The transverse internal force and its effective distribution width of top plate in reinforced concrete box girder under wheel load are studied in this paper. Based on the analytical results of box girder from finite element method, the expirical formulae for the determination of the transverse internal force and its effective distribution width of box girder are developed in which the global transverse rigidity of the box girder is included and the results from the formulae are compared with those from the present China Highway Bridge Specification and finite element analysis. |
