Tunnel lining is designed and constructed mainly based on the past experience. Considering mechanical characteristic to lining and the development of anti-frost method tunnels in cold region lead to a proper structure, and it can reduce the cost of construction. The principal results of this study are summarized as follows :1.Proposal of newly confinement curve : In this study, the newly confinement curve for support (namely stiffness of support) is developed. To this end, the tunnel is idealized as a perfectly cylindrical thin shell with two stiffening steel rings at ends. The mainly results are as follows:(1)The results for the stiffness of support obtained by this study are less than the ones obtained by the thin ring theory; the maximum error is 20 percent.(2)The effect of stiffening steel ring may be presented in terms of an effective width (0.35〜1)L where L is the length between two rings.2.Estimation of temperature overall the length at tunnels in cold region : For heat insulator design at road tunnel in cold region, it is necessary to estimate and/or determine the lowest (periodical) temperatures overall the length at tunnel. An equation for estimating temperature by a theoretical analysis considering heat convection/conduction between the tunnel-ground and the air flow is presented. From this study, the following results are obtained;(1)The calculated values well agree with the observed ones.(2)We can reasonably determine the necessary length of anti-frost treatment from tunnel entrance.

隧道衬里的设计和建造主要基于过去的经验。考虑到机械特征的衬里特征和寒冷区域中抗果实方法隧道的发展会导致适当的结构，并且可以降低施工成本。这项研究的主要结果总结如下：1。新限制曲线的掌握：在这项研究中，开发了新的限制曲线（即支持的刚度）。为此，隧道被理想化为完美的圆柱薄壳，末端有两个僵硬的钢环。主要结果如下：（1）本研究获得的支撑刚度的结果小于薄环理论获得的结果； the maximum error is 20 percent.(2)The effect of stiffening steel ring may be presented in terms of an effective width (0.35~1)L where L is the length between two rings.2.Estimation of temperature overall the length at tunnels in cold region : For heat insulator design at road tunnel in cold region, it is necessary to estimate and/or determine the lowest (periodical) temperatures overall the length at tunnel.考虑到隧道地面和气流之间的热转化/传导，通过理论分析来估计温度的方程式。从这项研究中，获得以下结果；（1）计算值与观察到的值非常吻合。（2）我们可以合理地确定隧道入口中抗果疗法的必要长度。
