The impact of the bridge is a key problem that affects the construction and operation of the bridge. Scholars have conducted a large amount of research on it and made positive progress. To promote research on the impact of bridges, the authors review the bridge collision events and the current situation of scientific research in 2019, summarize the current analysis hot spots from three aspects of ship collision, rockfall impact and vehicle collision, look forward to the research trend of bridge collision disaster, prevention and control, and the research trend of bridge impact disaster and prevention and control from the aspects of existing research expansion, new materials, new structures and new theoretical methods, among which the introduction of peridynamic research method will open a new window for the mechanism analysis of bridge collision. Among them, the introduction of peridynamic research method will help to deepen the understanding of the nature of collision, and provide a new path for the analysis of bridge impact problems to break through the bottleneck of traditional thinking.
