Review on China's Bridge Engineering Research:2021

In order to promote the development of China's bridge engineering subject,the academic research status,hot issues,existing problems,corresponding countermeasures and development prospects about bridge engineering at home and abroad(including bridge structural design,new bridge construction technology,bridge disaster prevention and mitigation)were studied systematically.Firstly,the progress of bridge engineering in academic researches were summarized in five aspects including high performance materials and structural systems,industrial and intelligent construction technology,disaster-resistant capability and deep water foundation.Secondly,all aspects of the above filed in bridge engineering were summarized systematically:steel bridge,composite bridge and deep water foundation in bridge structural design;new construction technology of steel bridges and accelerated bridge construction technology of RC bridges;seismic resistance,wind resistance,fire resistance and anti-collision in bridge disaster prevention and mitigation,as well as the corresponding development prospects.Hopefully,this paper is supposed to provide new perspectives and basic data for academic researches and engineering practice on bridge engineering subject.
