The execution with respect to tunnel structure has been carried out more important than maintenance until present time. There is a lot of interests on the maintenance of institution that is used by the nation, because of the recent miserable accidents. Consequently there need an organizational and efficient system. This paper has presented the sort, source and part of damage of tunnel structures etc. and then performed to analyze about the special quality of tunnel structure through input detailed safety assessment report data as well as fulfilment statical analysis. In conclusion, the paper"s intention is presenting the maintenance system base on those.

We must notice ground movement by excavation for reasonable tunnel designs. The convergence confinement method is an attempt to evaluate tunnel stability conditions by means of a mathematical model and a ground response curve. In this study, the convergence confinement method by numerical model was examined. This method don't need the basic assumptions for a mathematical model of circular tunnel shape, and hydrostatic in situ stress. Also modified ground response curve that is calculated after installing the support, is suggested, which informs us the ground movement mechanism. The ground response curve and the support reaction curve are mutually dependent. Especially the support reaction curve depends upon the ground response curve. The mechanism of tunnel must be analyzed by the interaction between support and ground. Consequently the stability of tunnel must be qualitatively investigated by a ground response curve and quantitatively adjudged by a numerical analysis for the reasonable design of tunnel.
