Abstract

The research was performed on the background of reconstruction and expansion project of Shandong 1# expressway, contrastive analyzed the changing status of Highway Engineering Technique Standard in regard to the bridge load revision adjustment, particularly computational analyzed the technical requirement and usability of the existing bridge. Combined the analysis of bridge detection and evaluation results, the reconstruction and expansion technology of the existing bridge was theoretical calculated and discussed. Finally, the reconstruction and expansion technical method and suggestion on the mechanical behavior changing character of the small span upper beam-slab and the bottom abutment were proposed. The instance analysis showed that, the small span bridge reconstruction and expansion technology has the advantage of economically feasible, environment protecting and technology feasible. Its specialty of short construction period, small effects, convenient for keeping traffic and meeting the demand of basic functions enables it with a large popularize prospect.
