摘　　要：文章基于南京纬三路过江通道工程实例,针对超大直径、超高水压、复杂地质与环境条件、高岩石强度掘进、高精度施工控制等特点和难点,介绍了其总体设计方案与关键技术。通过对隧道平面、纵断面、横断面及土建结构等设计进行综合分析,再结合对勘察设计关键技术问题的研究,对设计方案进行了优化,使项目总体功能和施工运营的安全性达到最优,对于提高我国大型公路水下盾构隧道建设水平具有重要借鉴意义。The general design proposal and key technologies of the Nanjing Weisan Road river-crossing tunnel project are introduced with respect to the engineering characteristics and difficulties encountered, such as a very large diameter, ultra-high water pressure, complex geological and environmental conditions, driving in high strength rocks, high-precision construction control and so on. By synthetically analyzing the original design op- tions of the tunnel plane, longitudinal profile, cross-section and civil structures and studying the key technologies for survey and design, the optimized final design option is proposed so that the overall function and safety of con- struction and operation can be best achieved. This paper is a significant reference for improving the construction of large-scale highway underwater shield tunnels.
