Abstract
Remaining life of tunnel can be predicted and optimum maintenance plan can be determined through Reliability estimation of in-service tunnel shield capacity. This article illustrates time-varying model of capacity parameters and modified methods of it and then builds a random process performance function of bearing capacity. Based on this, the methods calculating reliability of both planning and in-service tunnels are analyzed. It can be drawn from the analysis that the reliability of in-service tunnels will be better than planning tunnels at the same situation.
