 note = {The exfoliation accident of concrete in tunnels has occurred in recent years, and it argues about the state of maintenance management. Although it is necessary to understand the performance of tunnel that is contributed by the designers, the rational maintenance management has not been clarified due to the indefinite factors in the design stage. In this study, a database for the management of road tunnels in Nagasaki is developed by using GIS which is linked with the deformation prediction system. Based on the numerical simulations considered the time-dependent deterioration of strength of the lining and the surrounding rocks, the rational maintenance time and reinforcement method have also been proposed., 長崎大学工学部研究報告 Vol.33(61) p. 115-122, 2003},
