Abstract: The development of intelligent tunneling control systems for shield tunneling faces many challenges, such as a lack of testing environment, interference between system testing and normal tunneling time, and difficult test under special conditions. Shield tunneling also faces various challenges, including various geological conditions, complex construction procedures, and collaborative effect between equipment and systems. Thus, the authors summarize the development experience of intelligent shield tunneling systems, and propose a technical solution for constructing an experimental testing environment for intelligent slurry shield tunneling system based on actual shield tunneling and historical engineering data considering the needs of multi-system collaborative control and multi-working condition comprehensive testing of slurry shield tunneling. Furthermore, the authors conduct overall design of the experimental system, calculation and analysis of primary parameters, and detailed structural design, thus developing an experimental system with multiple functions including cutterhead resistance torque loading, propulsion resistance loading, and slurry circulation control. Preliminary tests are conducted as well. The results show that the experimental system can be used to load and test the shield, simulate excavation under different geological and working conditions, and provide a safe, efficient, flexible, and diverse experimental environment for the research of intelligent excavation algorithms and the development of intelligent control systems for shield tunneling.
