摘　　要：海底隧道的建设受工程地质众多因素的影响,盾构法施工过程中刀具极易损坏,需要及时在地层中进行带压开仓换刀工作,该过程还受多因素影响,需要不断改进技术方法以应对施工过程中遇到的各种阻碍。以陆丰核电项目为研究案例,以控风险、抓安全为原则,对第一海底带压开仓过程中遇到的风险及采取的安全质量控制措施进行施工总结,对后续的类似工程项目提供一定借鉴和指导意义。The construction of submarine tunnels is influenced by various engineering geological factors.During the shield tunneling process,cutters are highly susceptible to damage,necessitating timely pressurized chamber opening for tool replacement within the stratum.This process is also influenced by multiple factors,requiring continuous improvement in technical methods to address various obstacles encountered during construction.Taking the Lufeng Nuclear Power Project as a case study and adhering to the principles of risk control and safety assurance,this paper summarizes the risks encountered and the safety and quality control measures adopted during the first pressurized chamber opening in a submarine environment.It provides reference and guidance for subsequent similar engineering projects.
