In recent years, the durability of concrete bridges has attracted extensive attention from researchers and has been one of the hot topics in bridge research. The durability of concrete bridges can affect the safety and service life of bridges directly. Currently, the research on the durability of concrete bridges is mainly divided into two aspects: (1) From the perspective of the damage mechanism of the materials, the damage modes and influence factors of the bridge component materials are studied and the influence mechanism of the durability of the concrete bridge materials is analyzed; (2) From the whole of the bridge structure, the design and evaluation of the durability of the bridge and the maintenance of the bridge are studied, and the methods to improve the durability of the concrete bridge structures are explored. In order to grasp the research trend on the durability of the concrete bridge, this paper reviewed the literature on the durability research of concrete bridges by domestic and foreign scholars in 2020, from the design of the concrete bridge, the durability of the concrete material research, the study of concrete bridge reinforcement corrosion and the durability of concrete bridge improving technology, the influence of different service environment on the durability of the bridge, performance evaluation and service life prediction. The research focus and development direction of the durability of concrete bridges in the future are discussed.
