摘要
关角隧道位于青藏铁路西格段,是我国目前最长的越岭铁路隧道。针对关角铁路隧道复杂地质的特点,提出了辅助坑道的设计原则。通过对斜井、竖井进行分析比较,确定斜井作为辅助坑道。文章详细地介绍了斜井的断面、内轮廓以及平导内轮廓、施工横通道内轮廓,制定了隧道施工综合成洞指标和指导性施工组织方案。通过对三个施工方案的分析比选,推荐了10座斜井加局部平导方案。
Design principles for access tunnels are drawn up in view of the characteristics of complicated geology of Guanjiao super-long tunnel. Inclined shafts were determined as access tunnels according to analyzing and contrasting them with vertical shafts. The cross-section and inner periphery of inclined shafts, inner periphery of parallel addit and lateral passages are presented in this article. Preferable option consisting of ten inclined shafts and a short parallell addit was chosen through analyzing and comparing three options.
