| 摘 要： | 以厦门市白城高架异型桥为背景,采用3种车辆荷载作用方式,对异型桥在工作荷栽的作用下的挠度与应力进行了分析,绘出了挠度和应力变化图.建立了桥梁的有机玻璃模型,将计算结果与实测的挠度与应力值进行了对比分析,得出了梁体截面在工作荷栽作用下的挠度和应力变化规律,为桥梁设计和施工提供指导.分析结果揭示了异型桥在车辆荷载的作用下,梁体应力危险截面与挠度最大值截面并不一致,同时分析结果也为桥梁的监测提供了依据,保证桥梁建成后的安全运行.

| Abstract: | Based on the construction practice of Baicheng viaduct in Xiamen City,the deflection and stress of alien bridges related working loads are analyzed by adopting tree kinds of vehicle loads,from which the deflection in envelope and the stress in envelope and the bridge of synthetic glass model are built.Comparing the calculated results with the measured results,the distributing rules of deflection and stress in beam body section are generated.In order to provide guidance for the bridges design and constructio... |
