| 摘 要： | 斜梁桥的构造和受力特点与直线桥有很大区别。以某箱型截面梁桥为例，介绍采用空间剪力柔性梁格法对多格室斜交箱梁桥结构分析的基本原理及方法，并对梁格法的关键问题-梁格划分和刚度等效、截面特性计算、建模时关键问题处理进行阐述，将梁格法计算结果与单梁法的计算结果对比，主要结论和方法可供同行参考。

| Abstract: | The structure and loading features of skew girder bridge differ a great deal from straight bridge.This paper based on some box type cross-section girder bridge as an example introduces basic principles and methods for analysis of structure of multi-cell heterotropic box girder bridge by means of the spatial shear-flexible grillage method,and expatiates critical problems such as grillage classification,stiffness equivalent and calculation of sectional characteristics in the grillage method and processing for... |
