广义梁格法在曲线梁桥分析中的应用

Application of Generalized Grillage Method in Curved Girder Bridge

以一等截面曲线梁为例,分别通过梁格法计算和模型实测获得各曲线梁跨中挠度横向分布影响线,经对比分析发现二者吻合较好,说明用梁格法分析等截面弯梁桥的主梁横向分布是可行的。

Taking a prismatic curved girder as an example, the transverse distribution influence line of mid-span deflection of each curved girder is obtained by the calculation of grillage method or actual measurement of model. By contrastive analysis on the two ways, the results are consistent well, which proves that it is feasible that using grillage method to analyze the transverse distribution of prismatic curved girder bridge＇s main girder.
