预制混凝土桥面板湿接缝构造形式研究

Review of Wet Joints between Precast Concrete Bridge Decks

湿接缝作为预制混凝土桥面板现场施工的主要环节和最容易出现病害的部位,直接影响到预制混凝土桥面板的施工速度和使用性能。为给预制混凝土桥面板湿接缝的设计研究提供参考和依据,从构造特点、试验研究、使用性能和施工性能,对钢板湿接缝、预应力钢筋湿接缝、普通钢筋湿接缝和超高性能混凝土湿接缝进行总结和分析。

As key links of on-site construction and the most vulnerable parts in precast concrete bridge decks, wet joints directly influence construction speed and serviceability of precast concrete bridge decks. In order to provide reference and basis for design and study of wet joints between precast concrete bridge decks, steel plate joint, post-tensioned Joint,reinforced joint and ultra high performance concrete joint are summarized and analysed from the aspect of construction features, experimental study, serviceability and constructability
