| Research Abstract |
The principal results of this study are summarized as follows :
(1) In order to determine the necessary length of anti-icicle treatment from tunnel entrance area, a theoretical equation for estimating the temperature in the tunnel has been proposed.
(2) A computational procedure has been proposed for the analysis for analyzing temperature stress using cylindrical shell theory taking consideration into temperature distribution tunnel's lining.
(3) In order understand of the characteristics of the stiffness of the support, a closed analytical equation for estimating the stiffness of the support of tunnel consisting of shotcrete and ribs.
