Abstract: With the construction of ecological corridor for the Yellow River, the crossing Tunnel construction of the Yellow River is urgent in Shandong Province. It is necessary to solve the problems of construction and security guarantee for the Rail-and-Road combined tunnel. In view of the factors of engineering environmental conditions and tunnel construction risks，the overall design and key techniques of the Jinan Jiluo Road North Extension Tunnel were summarized and analyzed by means of engineering analogy, modeling and numerical testing methods．The results showed that the innovation and application of collaborative evacuation technology and ventilation scheme were used, which realized the intensive layout design of shield tunnel section. The design methods of distributed concave-convex tenon structure and integrated waterproof were used. And the overall stiffness and bearing capacity of shield tunnel were improved by considering the internal structure effect of segment and non-closed lining. The available closing time of anti-flooding door was calculated, which provided a theoretical basis for design of tunnel anti-flooding system. Through design of prefabricated and superimposed lane slab and prefabricated box culvert with adjustable height, the section diameter of shield tunnel was controlled, and the construction speed of internal structure was accelerated. After on-site verification, the construction risks were controllable and the overall design scheme was reasonable.

Key words: underwater shield tunnel joint construction of highway and rail underpassing reservoir risk control key techniques
