加强初期支护理念在现场实际施工中的应用

On application of strengthening early support in field construction

以某隧道工程施工为例,针对正洞衬砌施工存在的困难,采取了加强初期支护的解决方案,确保了隧道开挖后洞身的稳定,解决了衬砌无法紧跟掌子面的施工问题,保证了隧道的施工安全和施工进度。

Taking some tunnel project as the example, the paper adopts the solution scheme for the strengthening early support according to the difficulties in lining construction of main tunnel, ensures the stability of the tunnel after the tunnel excavation, solves the construction problem, that is, the lining can not follow the tunnel face, and guarantees the construction safety and the progress of the tunnel.
