Perspectives in Intelligentization of Tunnel Boring Machine (TBM)（对全断面隧道掘进装备智能化的一些思考）

The development status of artificial intelligence (AI) technologies, the development trend of intelligent engineering machines and the urgent national needs for the future intelligent TBMs are introduced briefly. It is pointed out that the intelligentization will be the hot spot of the tunnel engineering area and the focuses of future industry competition. The scientific challenges due to the complexity of the working environment, including state recognition and environment perception, correlation law between geological environment and operation parameters, intelligent planning and coordinated control of multi systems, are raised. In addition, the existing research foundation are analyzed and the inadequacy of the theory including environment and state perception, adaptive & dynamic control of construction parameters, multi system coordination control and multi objective optimization are obtained. At last, some thinking from the aspects of design, manufacture and operation, such as excavation perception, the adaptive dynamic control of excavation parameter condition, the excavation parameter data collection and calculation, intelligent optimization and decision making of tunneling parameters and the multi system coordination intelligent control are proposed.
