基于桥面板疲劳计算的多箱室钢桥横隔板设置

Diaphragm Setting of Multi-chamber Steel Bridge Based on Fatigue Calculation of Bridge Deck

结合实际设计项目,考虑桥位腐蚀环境和跨铁路因素的特殊要求,从钢箱梁顶板疲劳验算的角度,计算分析横隔板数量对顶板疲劳应力幅的影响,从而为同类项目优化横隔板数量提供参考方法。

Combined with an actual deign project,considering the special requirements of corrosive environment at the bridge location and the cross-railway factors,and from the perspective of fatigue calculation of the steel box girder roof,the influence of diaphragm number on the fatigue stress amplitude is calculated and analyzed so as to provide the reference methods for optimizing the number of diaphragms in the similar projects.
