ABSTRACT
In this paper, the environmental effects of prestressed concrete members of bridges are taken as the research object. The surface environmental effects of prestressed concrete members of bridges are analyzed from the perspective of the contact mode and erosion degree of environmentally corrosive media of prestressed members, and the durability of prestressed concrete members of bridges is affected. The main environmental factors of service life determine the typical environmental action categories, action levels and zoning of prestressed concrete members of bridges, thereby providing a basis for the design life of prestressed concrete members.
