For the construction, maintenance and reinforcement of the tunnels, the new concept called asset management has been introduced and paid attention recently. For the asset management, the key issue is how to define, monitor and assess the performance of the tunnels. The newly developed three-dimensional Underground Space Information Management System (USIMS) enables to store and integrate all types of information related to the construction, inspection, maintenance and reinforcement systematically with a 3-D virtual world. In this study, for the purpose of the tunnel maintenance and health assessment of the tunnels, the comprehensive tunnel database was constructed using USIMS based on the geological data at the tunnel site, construction data, regular inspection records and photos, and etc., which were stored as a hard copy and/or digital format. By updating this tunnel database, time evolution of the tunnel status such as deformation etc. can be presented with clear 3D vision.
