In this study, the behavior of urban subway tunnels is measured using instrumentation sensors installed in the lining concrete inside subway tunnels in order to analyze their behavior according to temperature variations. It is observed that the stresses of the concrete lining, tunnel convergence, and cracks change according to the temperature variations. However, the crack deformation differs depending on the size and status of the crack. In addition, this study proposes a correction formula
