In cold regions, existing tunnels constructed by sheet pile method suffer from frozen damages. In order to estimate these damages, analysis of temperature stress is necessary. This paper presents a method for analyzing temperature stress using cylindrical shell theory taking consideration into temperature distribution in tunnel's lining. The temperature distribution in lining is obtained using theoretical model of heat convection/conduction. The effects of geometrical parameters such as length, radius, and thickness of lining are investigated. Several examples are also compared with other numerical methods based on the cylindrical shell theory.
