| 摘 要： | 本文提出的隧道断面合理轴线的确定方法,并不涉及繁重的内力计算,而是从合理拱轴的概念出发,用三次样条函数来描述断面的合理轴线.它与传统的设计方法所提出的常见断面相比较,受力与变形均有明显改善.

| Abstract: | This paper proposes a method to determine a rational axis of the tunnel's section without involving complicated computation of interanl forces. It proceeds from the conception of rational arch axis and takes cubic sample slice function to describe and seek. Compared with the common section designed with traditional method, the conditions of the axis on the resistance and deformation are better. |
