In Japan, the construction of social infrastructure has been increasing since the high economic growth in the 1960s. Right now it is a problem in Japan that these infrastructures are deteriorating. It is expected that further deterioration will occur in the future and the maintenance and the effective operation for these infrastructures are now emerging the significant subjects. Under these circumstances, a managing method named as an infrastructure asset management is beginning to be employed recently. Infrastructure asset management is a strategic management of public and private physical assets including subway tunnels during their use in the society, which enables us to manage physical assets effectively and efficiently. The goal aimed at this paper is to conduct a mid and long term efficient maintenance and operation plan for the subway tunnels and to decide the proper budget for rehabilitation.
