For the damage situation of reinforced concrete high bridge piers' performance in corrosive environmental effects, a systematic evaluation system was established which can reflect corrosion damage condition of reinforced concrete high bridge piers, and fuzzy comprehensive evaluation model of the reinforced concrete high bridge piers' corrosion damage condition was established based on each index weighting factor analyzed by the way of Analytic Hierarchy Process (AHP). With the aid of field test data of a existing high bridge pier in corrosive environment and based on fuzzy comprehensive evaluation model, fuzzy comprehensive evaluation was made to the existing high bridge piers' performance. The case evaluation of overall quality is "slight damage". The project example shows that fuzzy evaluation is significance for project, as a way to evaluate corrosion damage situation of reinforced concrete high bridge piers' performance.
