摘　　要：盾构机掘进状态的准确预测和参数控制是盾构掘进系统管控的重点,针对这个问题,建立与掘进系统一致且同步的虚拟模型是解决问题的关键。为了实现对盾构掘进系统的智能管控,本文将能够实现虚实交互、适用于设备智能化的数字孪生技术引入盾构掘进系统中,依据掘进系统的相关需求,构建盾构掘进系统的数字孪生框架,通过虚拟模型和物理实体的实时映射实现信息交互,并依托于掘进系统服务应用层,设计了掘进载荷超前预测系统和盾构施工参数控制决策系统,为盾构掘进系统提供智能决策,实现盾构隧道掘进施工的智能管控。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.
