    摘要:

    纤维增强复合材料(FRP)因其卓越性能适应现代桥梁结构大跨、轻质、耐久的发展需求,近年来被广泛应用于桥梁工程。为促进复合材料桥梁领域的结构形式和设计的发展,从FRP材料性能、构件和桥梁结构3个层次对近年来FRP在桥梁工程中的研究和应用进行回顾,阐述FRP材料-结构一体化设计理念,并对FRP材料在桥梁加固、组合构件、全桥结构等方面的相关研究进行总结与评述。结果表明:现阶段桥梁用FRP仍局限于旧桥加固,新建大跨桥梁结构应用潜力巨大,需提高材料的力学性能、降低成本、制定产品质量检测标准,建立材料-结构一体化的设计、施工、监测规范体系和工程应用模式。

    Abstract:

    Fiber-reinforced polymer(FRP) has been widely used in modern bridge engineering in recent years due to the excellent material properties that can adapt to the development needs of modern bridge structures towards large spans, light weight, and durability. In order to promote the development of structural forms and designs in the field of bridges using composite materials, this article reviews the research and application of FRP in bridge engineering in recent years from three levels of FRP material properties, structural components and bridge structures. The design concept of FRP material-structure integration is elaborated in detail, and the relevant research of FRP materials in bridge reinforcements, composite components and bridge structures are summarized and commented.The results show that, the current application of FRP in bridge engineering is still limited in the rehibitation and has great potentials in implementing long-span bridges. It is necessary to improve FRP performance and reduce costs as well as formulate product quality inspection standards. Moreover,systematic codes and engineering applications should be established for design, construction and monitor based on the material-structure integration.
