QUALITY CONTROL OF PRESTRESSED REINFORCED CONCRETE AND CORROSION AND DAMAGE OF STEEL BARS
Taking Heifenggou bridge as an example,the paper evaluates and diagnoses the status of bridge structure.In the previous bridge inspection,the corrosion damage of KA beam prestressed cable is found,the degree of corrosion damage of prestressed steel bar is evaluated,the chloride ion in the bearing structure concrete is evaluated,and the corrosion evaluation of prestressed steel bar is made in detail.On this basis,some new materials are put forward the feasibility method of material(UHPC)for bridge reconstruction,which can provide reference for similar engineering construction.
