| 摘 要： | 采用三维有限元分析技术，对大跨径混凝土斜拉桥桥面铺装体系进行了三个层次的力学分析，即：桥梁结构整体变形对桥面铺装作用；应用于模型法分析轮载作用下桥面板局部变形特点，同时与建立的普通路面结构计算模型弯沉进行对比，从弯沉角度分析桥面铺装对沥青混凝土的性能要求；铺装层结构体系内部受力状态．总结出了大跨径混凝土桥梁桥面铺装受力特点，粘结层在铺装层体系中的关键作用．

| Abstract: | The stress state of the bridge deck overlay of a long span concrete cable-stayed bridge is analyzed from three levels of view points. The first analysis level is the effect of the deformation of the whole bridge. The second is the analysis of the local deformation of bridge deck under tyre load through submodeling, And the property of overlay asphalt is analyzed by comparing the deflection of bridge deck with the deflection of ordinary road structure. The third level is the analysis of internal stress state of deck overlay. The stress character of the deck overlay of a long span concrete bridge is summarized, and the key function of binding course in bridge deck overlay system is then analyzed. |

| Keywords: | bridge deck overlay finite element submodeling cable-stayed bridge |
