This paper explores the influencing factors, mechanical mechanism and evaluation model of "machine-rock" cooperative mapping in dual-mode shield (TBM-EPB) tunnel construction, and scientifically determines the order parameters of artificial and natural interaction system evolution in dual-mode shield (TBM-EPB) tunnel construction by means of mechanics and Synergetics, and establishes a "machine-rock" cooperative mapping evaluation model for dual-mode shield (TBM-EPB) tunnel construction. The "machine-rock" cooperative mapping of dual-mode shield (TBM-EPB) tunnel construction is evaluated by computer, and verified by a typical case of efficient and safe construction of dual-mode shield (TBM-EPB) tunnel between Liuxiandong Station and Baimang Station of Shenzhen Metro Line 13. Finally, the future development trend and key technologies of dual-mode shield (TBM-EPB) tunnel construction are predicted, and the future research trends. The results of this paper have important guiding significance for the toughening construction of underground tunnel and its cooperative coexistence with the environment.
Urban ground traffic congestion has become one of the main problems in super-first-line, first-line and other major cities at home and abroad, and the development and use of urban underground space transportation resources has gradually become the focus and focus of urban transportation construction. However, urban subway tunnels are mostly built in urban areas with dense personnel, vertical and horizontal traffic flow and numerous buildings, and their construction is underground covert engineering, and there are many uncertainties in underground engineering geological conditions. Tunnel construction is very easy to cause collapse accidents (figure 1). In order to avoid the above disaster problems, the industry is increasingly using the shield method for underground tunnel construction. In the process of urban subway tunnel construction, shield method has been widely used in the development of urban underground rail transit because of its characteristics such as small environmental impact, high tunneling efficiency and high construction safety.
