| 摘 要： | 小净距隧道是继分离式隧道、连拱隧道后出现的一种适应性较强的新型隧道形式，我国已有一定的成功经验，表现出其良好的安全、经济实用性。随着我国高等级公路的发展，小净距公路隧道将成为高等级公路隧道的重要组成部分。通过对国内外小净距隧道合理净距的研究、对施工对策等方面的进展情况进行的分析，指出了小净距公路隧道设计施工中亟待解决的问题。

| Abstract: | Compared to separated tunnel and double - arch tunnel, the closely spaced tunnel is a new tunnel form in practice, with higher applicability and safety. Much valuable experience has been obtained in their construction. With the development of highway, closely spaced tunnels will be adopted widely and become an important part of highway tunnels. The progress in study on the optimal distance, construction technologies is presented. Some key problems in design and construction of closely spaced tunnels were put forward at last. |

| Keywords: | closely spaced tunnel tunnel stability optimal distance interval pillar |
