从新建隧道与既有隧道之间的合理岩柱的留设、新建隧道的施工方法以及支护方式等方面，采用数值模拟的方法，分析邻近既有平风岭隧道的新建新平风岭隧道的稳定性控制问题，提出留设8m岩柱、采用单侧壁导坑施工方法、侧向45°超前小导管加固的一体化稳定性控制对策。
從新建隧道與既有隧道之間的閤理巖柱的留設、新建隧道的施工方法以及支護方式等方麵，採用數值模擬的方法，分析鄰近既有平風嶺隧道的新建新平風嶺隧道的穩定性控製問題，提齣留設8m巖柱、採用單側壁導坑施工方法、側嚮45°超前小導管加固的一體化穩定性控製對策。

The issues of stability control of the newly-built Pingfengling Tunnel adjacent to the existing Pingfengling Tunnel were analyzed by means of numerical simulation, in terms of the rock pillar’s reserving between the two tunnels, the construction method for the newly-built one, the support forms and so on. As a result, an integrative control measure of tunnel stability has been proposed, such as reserving 8 m rock pillar, using single side drift method, and using advanced small ducts to laterally strengthen in 45°direction of tunnel axis.
