| 摘 要： | 为加快隧道施工进度通常需长隧短打,而辅助坑道形式的合理选择是实现这一手段的关键。以新建的兰渝铁路肖家梁隧道工程为背景,根据各影响施工因素的比选和分析,提出了隧道辅助坑道的最优方案。并从隧道主要矛盾是瓦斯的具体情况出发,最终采用"竖井+斜井方案",最大限度地解决了工期问题。

| Abstract: | It often requires construction of long tunnel by means of driving from adit to accelerate tunnel construction schedule,and reasonable auxiliary gallery form is the key to realize this.In this paper,based on the newly built Lanzhou-Chongqing Railway Xiaojialiang Tunnel,through comparison and analysis of each influencing factor of construction,the optimal program of tunnel auxiliary gallery is put forward.For gas is the main contradiction of tunnel,the program of inclined shaft combined with vertical shaft is finally adopted,which farthest solves the problem of construction period. |

| Keywords: | tunnel auxiliary gallery parallel adit inclined shaft vertical shaft program comparison |
