Abstract The Yellow River Tunnel located on Jiluo Road in Jinan is one of the largest road-rail joint tunnels which are currently constructed in China. It is the first super-large-diameter shield tunnel to cross over the river suspended above ground in the world. The project had some characteristics, such as large shield excavation section, long excavation distance, shallow overburden, high water pressure, deep working shaft foundation pit, and high protection requirements for surrounding structures. Based on engineering construction environment and construction risks, the overall design plan of the Yellow River Tunnel was analyzed, which included engineering horizontal and vertical section design, cross section layout, environmental risk controlling, tunnel structure and construction organization. The design schemes of super-large-diameter shield tunnel suitable for the middle and lower reaches of the Yellow River were determined. The design ideas and engineering features of the tunnel across the Yellow River on Jiluo Road in Jinan city was introduced, which provided reference for similar engineering design.
