摘　　要：为研究如何减少隧道穿江造成的防洪影响,以南京地铁4号线二期工程为例,从河势演变、渗流和堤防变形3方面展开分析,在此基础上提出补偿措施和设计方案,并总结施工要点,以期为类似工程提供参考。结果表明:隧道建设对工程区河段的防洪影响较小,但不利水文条件下的河势演变可能会威胁隧道自身安全;采用抛石防护和注浆加固可进一步稳定河势、提高堤防防渗和抗变形能力;严格遵守技术规范、优化流程和工艺是保证施工质量的关键。To study how to reduce the flood control impact caused by the tunnel crossing the river,taking the second phase project of Nanjing Metro Line 4 as an example,an analysis was carried out from three aspects:river regime evolution,seepage,and dike deformation.On this basis,compensation measures and design schemes were proposed,and the key construction points were summarized,aiming to provide references for similar projects.The results show that the construction of the tunnel has a relatively small impact on flood control in the river section of the project area.However,the evolution of the river regime under adverse hydrological conditions may pose a threat to the safety of the tunnel itself.The application of riprap protection and grouting reinforcement can further stabilize the river regime and enhance the anti-seepage and deformation resistance capabilities of the dike.Strictly adhering to technical specifications and optimizing processes and techniques are the keys to ensuring the construction quality.
