| 摘 要： | 以双口面支渠1#公路桥为例,用有限元程序计算分析宽幅扁平钢箱梁中中腹板厚度变化对剪力滞效应的影响,解决了本桥设计时亟需确定的中腹板的设置问题,并得出单肋斜跨拱吊点处顶板和底板有应力集中的结论,说明索力对应力的分布影响较大,这为以后类似桥梁的设计提供参考依据.

| Abstract: | Based on Shuang Kou Mian Zhi Qu 1# bridge,through finite element method,the effects of the width of web plate on shear lag effect are calculated and analyzed and the setting problem of web plate in design solved.The study shows that significant stress concentration exists in both top and bottom of girder and the study provides reference for future design. |
