摘要 基于折面梁格法对宽箱梁桥的受力特性及梁格尺寸划分进行分析,将折面梁格法计算的汽车荷载横向分布效应与常用结构计算方法的计算结果进行对比分析,验证该计算方法可以在宽箱梁桥计算方面达到实用性以及精细化分析的目的。并探讨性地应用折面梁格法计算宽箱梁桥的阶梯形剪力滞效应,同时研究折面梁格法建模的纵、横向梁格尺寸划分的原则。 In this paper,the mechanical characteristics and beam grid size division of wide box girder bridge are analyzed and studied based on the folded grillage method.The transverse distribution effect of vehicle load calculated by the folded grillage method is compared with the result calculated by the common structural calculation method.It is verified that the calculation method can achieve the purpose of practicality and refinement analysis in the calculation of wide box girder bridge.At the same time,the paper studies the principle of dividing the size of longitudinal and transverse beam grids for similar projects.
