摘　　要：通过有限元模拟对正交异性桥面板构造对钢桥面铺装荷载响应的影响进行分析,结果表明:纵腹板部位、顶板变厚度部位对铺装的荷载响应具有显著影响,这些刚度突变部位是钢桥面铺装受力分析的临界荷位;行车状态对荷载响应也有明显的影响。This paper analyzes the influences of structure of orthotropic deck plates on load response of steel deck pavement via finite element simulation, the results show that longitudinal web part and thickness variable part of top plate have remarkable influences on load response of pavement, and these parts with sudden change of rigidity are critical loading parts in analysis of stress on steel deck pavement;the driving status also exhibits obvious influences on load response.

关 键 词：正交异性板 钢桥面铺装 荷载响应 临界荷位
