| 摘 要： | 对各向异性钢桥面铺装层损伤破坏的调查表明,桥面板与纵向主梁及加劲肋连接处上方的铺装层表面易产生纵向裂纹。在一系列假设的基础上,通过简化模型分析了铺装层的这种破坏机理。分别从横隔板间距、钢板层厚度、铺装层厚度、加劲肋刚度及铺装层材料特性等方面对铺装层的耐久性进行了研究。

| Abstract: | Many of inspection reports on asphalt pavements on orthotropic decks of steel bridges have shown that the pavements above main girders and ribs were ease to form longitudinal cracks.Based on a series of assumptions,a simplified model was used for analysis the character of pavement damages.The durability of asphalt pavements on orthotropic decks of steel bridges was researched from the aspect of the thick of deck plate,the thick of pavement,the stiffness of ribs and the material properties of pavements. |
