【Abstract】Firstly, the main technical challenges, i. e. fabrication of steel tube, placement of self-compaction concrete, quantitative check of compactness of self-compaction concrete and long-distance floating transportation of steel tube, in steel-concrete-steel composite immersed tunnels during industrialized and intelligent construction of Shenzhen-Zhongshan Link are analyzed. And then the construction philosophy of “standardization, industrialization, assembly, intellectualization, and refinement” is proposed, and the intelligent construction system for immersed tunnel of Shenzhen-Zhongshan Link is planned so as to ensure high-quality construction, reduce the risk, and guarantee the time control in the whole construction. Finally, discussion is made from the aspects of intelligent fabrication of immersed steel tube element, intelligent placement of concrete, smart detection, intelligent installation of tubes and intelligent construction sites, etc.
