| 摘 要： | 互通变宽桥的构造处理和结构计算通常复杂繁琐,很长一段时间会困扰着广大的结构设计人员。通过对某匝道变宽桥的单梁模型、梁格法模型以及实体模型的对比,可以得出该桥梁格法模型的纵向刚度和横向刚度模拟能满足工程计算的整体精度要求,计算的结果可以作为设计依据,为今后同类型桥梁的构造处理和结构计算提供借鉴和参考。

| Abstract: | Through the comparison of single-beam model, grillage model and entity model for a ramp broaden bridge, this paper concluded that the longitudinal stiffness and transverse stiffness simulation of the bridge grillage model could satisfy the overall accuracy requirement of the engineering calculation, the calculation results couht be used as design basis, which also provided the reference for the structural treatment and calculation of the same type bridge in the future. |
