Application of a New Prestressing Technology in the Maintenance of Highway Bridges
Over time,highway bridges will have disease problems in operation,which will affect their normal use and easily cause serious safety accidents,so this paper proposes the application of a new prestressing technology in highway bridge maintenance.It analyzes the advantages of applying the new prestressing technology in the mainte-nance of highway bridges and avoids the problems of this technology during construction through its key applica-tion points.Finally,it clarifies that in the maintenance of highway bridges,the pre-tensioned prestressing technol-ogy can be used to prefabricate maintenance components,the unbonded prestressing technology can connect con-crete box girders,and that the prestressed carbon fiber reinforced plastic(CFRP)reinforcement technology can be applied to the maintenance and reinforcement construction of bridges.This paper makes an in-depth analysis of the key points of this technology,which lays a solid foundation for its application and promotion in practice.
