To understand the development trend of the research of bridge hydrodynamics and on the basis of summarizing its research contents, methods and achievements, the follow-up research will be carried out better, this paper reviews the recent literatures published in 2020 from the aspects of wave current effect, local scour of foundation, fluid solid coupling, multi disaster effect of extreme marine environment, etc. It is found that the research hotspots of bridge hydrodynamics mainly focus on the models of an extreme wave, current action, and wave-current interaction, the influence factors and depth prediction of pier local scour, the fluid-structure coupling of the deep-water bridge under earthquake action, the combined effort of wind and wave Disaster assessment and risk analysis of bridge in an extreme marine environment, response analysis and optimization design of long-span floating bridge structure. By combing the shortcomings of the existing research, the following urgent research directions are proposed: structural fluid-structure coupling in extreme wave and current environment, pier erosion monitoring and protection, intelligent and information-based bridge hydrodynamic disaster prediction, and multi disaster research. It is expected to make joint efforts with relevant scholars to contribute to the development of bridge hydrodynamics.
