摘　　要：霞浦隧道F1断层富水而破碎,施工中发生塌方和涌水的可能性很大。对此采用超前地质探查、超前预注浆阻水、加设大管棚、加强初期支护、加固圈3m全断面径向注浆、加强防、排水等一系列综合治理措施,成功地通过了F1断层。施工经验可供同类工程参考。The F1 fault through which the Xiapu Tunnel goes is watery and broken, which is most likely to result in collapse and gush of underground water in the process of construction. With the poor geological conditions taken into account, taken are a few comprehensive treatment measures, such as the advanced geological exploration, pre-slip-casting concrete to stop water, building the large-tube shed,strengthening the initial support, fuU-section radial slip casting concrete onto the 3 m strengthening ring, strengthening the prevention and draining of karst water, etc. , all of which help the tunnel to go smoothly through the fault. The construction experience of the project may serve as a useful reference for other similar projects.
