 note = {The authors propose a maintenance management system for RC subway tunnels suffering from chloride and carbonation induced corrosion. The proposed system consists of three subsystems. Firstly, by using numerical predictive models coupled with on-site measurement information, the engineering evaluation sub-system estimates or predicts the degree of deterioration of RC tunnel sections due to steel corrosion induced by carbonation and chloride ions. Then, in the maintenance prioritization subsystem, priorities are assigned to preventive maintenance and distressed concrete repair using preset thresholds. Finally, the project planning system is executed to allocate preventive maintenance and repairs on a year-by-year basis within imposed budget constraints. Through a couple of case studies, the proposed system is shown to be capable of managing structure data and on-site inspection results in an integrated manner and it is demonstrated to be helpful in drawing up maintenance management plans under various conditions.},
