The accurate prediction and parameter control are the key points of shield tunneling system control,hence it is crucial to establish a virtual model which is consistent and synchronous with the tunneling system.In order to realize the intelligent control of the shield tunneling system,this paper introduces the digital twin technology and suitable intelligent equipment into the shield tunneling system to achieve the virtual and real interaction.According to the related requirements of tunneling system,the paper also constructs the digital twin framework of shield tunneling system.Based on the real-time mapping between virtual model and physical entity,the information interaction is realized.Moreover,the paper designs the tunneling load advance prediction system and the shield tunneling construction parameter control and decision system under the service application layer of the tunneling system.,which can help intelligent decision-making for shield tunneling system and reach the intelligent management and control of shield tunneling construction.
