摘要
介绍莆田市外渡引水工程隧洞开挖中对所遇断层的处理情况 .开挖前对所发现断层预先做了固结土体和超前支护防治 ,使断层带在开挖中处于稳定状态 ,隧洞施工得以安全顺利进行 .这一方法对解决各种地质条件下土洞开挖的施工困难具有一定的借鉴价值 .
This paper introduces the treatment technology of faults encountered during tunneling in the Putian water diversion Project. Particular measures such as consolidation of earth mass and support in advance have been taken before the commencement of excavation in order to keep the fault zone in a steady condition while tunneling. Safety construction was successfully guaranteed, and the approaches adopted are recommendable to various geological conditions which may cause difficulty to earth tunnel construction.
