    摘要:

    为了解过去一年混凝土桥及其高性能材料研究方向的发展动态,并在总结其研究内容、方法和成果的基础上更好地开展后续研究,从混凝土桥、高性能混凝土材料及高性能加劲筋材三方面着手,查阅了近期文献,并进行了分类、总结和评述。研究发现:目前,混凝土桥方向更加注重其耐久性、全寿命周期设计、寿命预测及极端环境下的性能劣化等问题;高性能混凝土材料方面更加注重绿色环保、增强增韧和自密实等性能研究;与其配套的高性能筋材则主要围绕强度更高、更耐久的FRP筋展开。对现有研究的不足和有待深化的问题提出初步建议,期待与相关学者共同努力,为该方向的进一步发展做出贡献。

    Abstract:

    In order to understand the development trend of the research direction of concrete bridge and its high-performance materials in the past year, and on the basis of summarizing the research contents, metholds and achievements, the follow-up reserch will be carried out better, this paper reviews the recent literatures from three aspects of concrete bridges, high-performance concrete materials and high-performance reinforced materials.Furthermore, the literatures are classified, summarized and commented.The results show that the current research on concrete bridges pays more attention to durability, life cycle design, life prediction and performance degradation in extreme environments.For high-performance concrete materials, more attention has been paid to research of green environmental protection, strength/toughness improvement and self-compaction. The related high-performance reinforced materials have been mainly focused on the FRP bars with higher strength and better durability. Finally, the paper points out shortcomings of the existing research and the work to be done in the future.
