摘要:
公路桥梁的伸缩装置是桥梁结构中最为脆弱的部件,不仅容易损坏,而且修复困难。文章综述了国内外无伸缩缝桥梁的发展历程,以及国内旧桥无缝化的工程案例及相关研究;总结了国内旧桥无缝化改造的常用设计方法,介绍了桥墩、桥台处的无缝化构造处理技术;同时对旧桥无缝化技术的工程意义、应用前景、存在问题进行分析,表明对旧桥进行无缝化改造可提高其承载力、行车舒适性和抗震性能,具有广阔的应用前景和重要的经济价值,也指出今后研究的方向和可能存在的技术难题。
Abstract:
The extension device of a highway bridge is the most vulnerable part of bridge structure, which is difficult to repair. The development process of domestic and foreign jointless bridges as well as the engineering cases of old jointless bridge and other related research were reviewed. Domestic common design methods of the jointless reconstruction of old bridges and the treatment technology of the jointless structure of the bridge pier and abutment were described. The engineering significance, application prospects and problems of the old bridge jointless reconstruction technology were analysed. The results show that the jointless reconstruction of the old bridges can improve the bearing capacity, driving comfortability and seismic performance of the bridges. The direction of future research and the technical problems in the reconstruction were discussed.
