| 摘 要： | 针对既有桥梁拓宽改造中新旧桥纵向接缝的若干关键问题,比如桥梁拼宽纵向接缝类型、拼宽桥梁整体和局部受力分析、收缩徐变和不均匀沉降影响、拼接时机选择、不中断交通的施工工艺以及特殊桥梁拼宽等问题,结合典型工程应用,进行了系统总结和归纳.以某连续梁桥为例,进行了两跨箱梁桥的1:4室内模型试验,分析比较纵向接缝中刚性连接与铰接连接的受力特点;进一步指出了该领域存在的问题和今后主要的研究方向,对于既有桥梁特别是高速公路桥梁的拓宽改造具有一定的参考价值.

| Abstract: | In this paper,some key problems of longitudinal connection joints between the widening new bridges and the existing old bridges were summarized and explained,such as the selection of longitudinal connection joint style,analysis of the local and the whole static/dynamic characteristics of the widening new bridges,influence analysis of the concrete shrinkage and creep,as well as the asymmetrical settlements between the widening new bridges and existing bridges.The time choice in which the widening new bridges... |
