针对青岛胶州湾海底隧道隧址区含水断层的地质特点,文章主要论述了采用超前地质预报进行预报,帷幕注浆、超前长管棚进行堵水预支护,以及采用台阶法进行开挖快速穿越含水断层的施工技术。并结合成功快速穿越F4-3断层的工程实例,具体介绍了针对胶州湾海底隧道含水断层的施工方案,同时在施工过程中根据实际揭露的地质反馈信息,随时进行动态设计、动态施工,这种信息化的工作方法既保证了施工安全,又加快了工程进度,对顺利穿越含水断层断层起到了至关重要的作用。
In view of the geological characteristics of the water cut in the tunnel area of Qingdao Jiaozhou Bay Submarine Tunnel, this paper mainly discusses the prediction of water quality by using advanced geological forecasting, curtain grouting, advanced water pipe pre-shoring, and the step-by- Fault construction technology. Combined with the successful case of F4-3 rapid succession, this paper introduces the construction scheme for the water cut of the Jiaozhou Bay Subsea Tunnel. At the same time, the dynamic design and dynamic construction are carried out at any time according to the actual geologic feedback, Informational working methods not only ensure the construction safety, but also speed up the progress of the project, which plays a crucial role in the smooth cross-section of water-bearing faults.
