    摘要:

    预制装配式结构具有施工速度快、占用场地少、构件质量高、建造过程绿色环保等显著优势,是实现建筑工业化的可靠途径,近年来获得了学界、工业界的高度重视。在桥梁工程领域,预制装配式混凝土桥梁结构得到了快速发展,针对预制装配式混凝土桥梁结构的研究快速增加,诸多新型预制装配式混凝土桥梁结构已应用于实际工程。总结2019年预制装配式混凝土桥梁结构的研究进展,从下部结构与上部结构两个方面论述了该领域内的新技术、新构造以及典型工程应用。经过总结发现:预制装配式桥墩的连接构造及其抗震性能是本领域的研究重点,也是阻碍装配式桥梁结构向高烈度地震区发展的关键问题;预制装配式上部结构中,基本预制构件之间的连接构造形式受到大量学者的关注,连接构造的抗裂能力,疲劳性能等有待进一步提升,旨在实现“等同现浇”的力学性能。

    Abstract:

    Prefabricated structure hasthe advantages of accelerating the construction, saving energy and resource, and mitigating the impact on the environment. Prefabricated structure is a reliable way to realize the industrialization of buildings. In recent years, researchers and design engineers have carried out studies on the prefabricated structure. In the field of bridge engineering, due to the rapid development of prefabricated concrete bridge structures, research on prefabricated concrete bridge structures has increased rapidly, and many new prefabricated concrete bridge structures have been applied in practical engineering. This paper presents state of the art on prefabricated concrete bridges in 2019, in views of prefabricated substructure and prefabricated superstructure to discuss the new technology, new structure and typical engineering applications in this field. From the summary of this paper, it was found that the structure of connection and seismic performance of prefabricated bridge piers are the focuses of the research in this field. It is also a key issue that hinders the construction of prefabricated bridge in high intensity region. In the prefabricated superstructure field, the connection structure between the basic prefabricated components has attracted a lot of researchers' attention. The crack resistance and fatigue performance of the connection structure need to be further improved, aiming to achieve the ‘emulative’ mechanical properties.
