Abstract: In this study, difficulties, challenges, and development significance of fullface tunnel boring machine(TBM) are analyzed. Then, the research and development status of intelligent manufacturing, intelligent operation, intelligent maintenance, intelligent installation, and robot application in fullface TBM industry are emphatically discussed and analyzed. Finally, the development directions of fullface TBM intelligent manufacturing and intelligent operation and maintenance technology are proposed as follows: (1) the establishment of a data sharing mechanism between equipment manufacturing and operation; (2) key technologies of multisource heterogeneous data acquisition, intelligent terminal development, and multilayer manufacturing production collaboration; (3) research and development mechanismdata hybrid driven cloud edge distributed intelligent operation and maintenance system that can promote the process of intelligent construction of tunnel engineering; and (4) establishment of a "Usercentered" MMO value network service platform across domains that can realize the transformation and upgrading of the fullface TBM industry.

Key words: fullface tunnel boring machine; intelligent manufacturing, intelligent operation and maintenance
