桥梁无缝化技术在西部地区的应用研究

Applied Research on Bridge Jointless Technology in the Western Region

简要综述桥梁无缝化技术在国内外的发展状况,重点介绍了交通部西部交通建设科技项目"无缝化技术在西部地区中小跨径桥梁上的应用研究"课题在实验依托工程中的设计、施工情况。同时,对这种新型无缝桥梁的加筋接线路面进行了受力及裂缝分析,可为我国西部地区公路中小桥梁建设中推广无缝化技术提供参考。

This paper reviews briefly the development of bridge jointless technology at home and abroad,introduces design and construction about the west traffic construction Science and technology project＂the jointless technology in western area medium and small span bridges on applied research＂in experiment based on engineering.At the same time,stress and crack analysis of reinforced pavement on new jointless bridge was given,provides reference for apply of the jointless technology on medium and small span bridges construction in the western region.
