The purpose of this study is to estimate the present and future condition of performance of civil engineering structure and then to propose the strategic maintenance system, which applied the risk engineering. When the maintenance is carried out, it is important to repair in the appropriate timing by monitoring the degradation of performance. In this study, the focus is especially put in tunnel structures, which the equivalent uncertainty will be accompanied in the estimation of the degradation process. Therefore, this uncertainty is expressed by the application of stochastic differential equation model. The uncertainty of the future condition is converted into the cost benefit by the concept of a risk, and the optimization of maintenance repair and renewal is done based on the LCC analysis.
