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.
