摘　　要：采用外加电流对混凝土构件中钢筋快速锈蚀,通过材性试验探讨了锈蚀钢筋力学性能,通过锈蚀钢筋混凝土构件荷载试验,探讨了钢筋锈蚀程度对混凝土构件的承载力、刚度的影响,有效地评估了锈蚀钢筋混凝土构件承载力的降低程度和耐久性。Accelerated corrosion test are carried out for reinforcing steels corroded in concrete by electrochemical method. Mechanical performance of corroded reinforcing steel way studied, through the load experinment of concrete members with corroded reinforcing steel. The influences of reinforcement corrosion on stiffness and load bearing capacity of the members are discussed. The study effectively evaluates the reduce level of the structure resistance and durability of reinforced concrete structure.
