摘　　要：文章介绍了别岩槽隧道茨竹垭(F1)大断层的地质背景、岩体构造、地下水等地质特性,详细论述了穿越该断层的相关工程措施:超前地质预测预报、超前帷幕注浆、超前大管棚注浆预支护、加强型复合式衬砌等,重点提出了帷幕注浆设计、施工的关键技术,对类似工程的设计与施工具有较高的参考价值。In this article the geological background, rock formation and groundwater condition related to Cizhuya fault （F1）are introduced. Corresponding engineering countermeasures are discussed in detail including advance geological prediction and forecast, advance curtain grouting, advance pipe-roofing, strengthened composite lining, etc. Key technologies about the design and implementation of curtain grouting are addressed. This will provide some instructions for similar projects.
