结合奥则焉隧道施工实例，主要介绍该隧道位于黄土浅埋偏压地段，土体含水量大，有滴水现象，通过对其施工技术进行论述，提出三台阶七步流水工法并详细介绍了相应的施工技术要点，可供类似工程参考。%Combining with the construction example of Aozeyan tunnel, this paper introduced in detail that the tunnel was located in loess shallow buried bias areas, soil water content was large, had water dripping phenomenon. Through the discussion to its construction techniques, put forward three stages seven steps flow method, and introduced in detail the corresponding construction techniques, could provide reference for similar engineering.
