摘　　要：提出了连拱隧道在地形斜交情况下半明半暗的设计思路,介绍了半明半暗连拱隧道设计的主要计算模拟过程,为山区高速公路连拱隧道减少边坡开挖,最大限度地保护自然环境,为陡坡地段连拱隧道的设计施工提供了一种新方法。This article raises design concept of half-embedded ＆ half-uncovered arcaded tunnel under the inclined crossing situation of landform. It introduces in details main calculative simulated process of halfembedded and half-uncovered tunnel, providing a new method for reducing side slope excavation of arcaded tunnel of mountainous expressway, protecting natural environment to the maximum degree and also for design ＆ construction of arcaded tunnel at steep slope section.
