结合厦门海底隧道方案研究与勘察设计的实践经验，对我国处于规划论证阶段的琼州海峡隧道、渤海湾海峡隧道以及台湾海峡隧道几座跨海峡海底隧道的关键建设技术进行初步讨论。通过多方面分析后认为，要顺利建成这几座跨海峡的海底隧道，必须在跨海控制测量、深海地质勘察、高水压力断层破碎带的开挖与衬砌、隧道快速掘进施工以及超长隧道单元的通风等方面有所突破。

According to the survey and design study of Xiamen Subsea Tunnel scheme, the author gives a primary discussion on key construction technologies of Qiongzhou Channel Tunnel, Bohai Strait Tunnel and Taiwan Strait Tunnel. In order to build the above subsea tunnels successfully, we must achieve technology breakthrough in seacrossing control survey, geological survey under deep ocean, excavation and lining in fault stratum with high water pressure, rapid tunnel excavation technology and ventilation of extralong tunnel unit.
