| 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 or- dinary road structure. The third level is the analysis of internal stress state of deck overlay. The stress charac- ter 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. |
