双连拱隧道在结构上与单拱隧道有较大区别，近年来逐渐被应用于高等级公路中。如何在其施工过程中把握要点，吸取经验教训，逐渐熟悉并掌握其施工工艺有着非常重要的意义。通过介绍元磨及思小高速公路隧道施工过程中的工艺控制，就双连拱隧道的结构特点、中导洞及三导洞开挖方法、衬砌施工、特殊问题的处理等内容，提出了看法及建议。

Doublearched tunnels, which have been adopted in highway works in recent years, have great difference from singlearched tunnels in respect of tunnel structures. Therefore, it is of great significance to understand the key points of doublearched tunnels and to learn from relevant experience and lessons so as to grasp the construction technology of doublearched tunnels. Taking the doublearched tunnels on YuanMo highway and SiXiao highway as example, the article expatiates on the structural features, central drift excavation method, threedrift excavation method, lining construction and some special issues of doublearched tunnels.
