摘要
依托某在建实体工程中需要利用旧空心板桥作为滑道顶推运输钢箱梁新桥结构项目,深入研究新旧结构在局部受压约束连接时二者的耦合受力性能,以及钢箱梁顶推时的合理布置位置。
Based on a physical project under construction, in which the old hollow slab bridge was used as a slide pusher to transport the steel box girder new bridge structure, the coupling mechanical behavior of new and old structures under local compression constraint and the reasonable placement of the steel box girder when pushing were studied.
