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 (JTJ0 2 3- 85 )进行了比较
Based on the overall deformation of the reinforced concrete box girder, the finite element analysis program was used to analyze the lateral force of the box girder roof and the flange plate under the tire load. Through regression analysis, The empirical formulas of the transverse bending moment and transverse force distribution width of the lower lane board with variable section parameters are compared and the empirical value is compared with the finite element value and the current bridge standard value (JTJ0 2 3-85) in our country
