Abstract

In this study, numerical analyses on cut-and-cover tunnel linin gs were performed using different modeling methodsoses were to find a relatively more reasonable modelingmethod and boundary conditions. The results of the study reveal ed problems associated with each modeling method andfactors influencing the behavior of cut-and-cover tunnel lining condition in a more rational way. It was indicated that, under the given conditions, displacements and member forcesoccurring on concrete lining could be different as much as 53% depending on the type of modeling method applied; andn of boundary conditions properly simulating actualfield conditions and verification of prediction based on instru mentation are essential for rational design and analysis.
