Analysis of the Chloride Erosion Model and Durability of Prestressed Concrete
Abstract：With regard to the durability problem of prestressed concrete structure under chlorine ion erosion,progress and achievement of modeling of chloride ingress at home and aboard were summarized,and several typical diffusion equations analyzed,and the prestressed concrete chloride ions erosion model improved.By taking chloride diffusion velocity,surface chloride concentration and thickness of concrete cover,as Analysis variables,the durability reliability analysis model was established.It was proposed that comprehensive measures should be taken to improve the prestressed concrete durability.
