Application and outlook of information and intelligence technology for safe and efficient TBM construction

Informatized and intelligentized TBM involves various technologies including communication, sensing, data mining and artificial intelligence technology, which are applied in different construction processes such as tunnelling, support and direction guide and provide an important support for safe and efficient TBM tunnelling. In consideration of main problems existing in the current construction process, this paper proposes an integrated technology application system to enable TBM informatized and intelligentized, which takes geology and TMB information perception as the basis, multi-source massive information fusion platform construction as the center and intelligent TBM excavation control as the application target. Then, the research and application condition of key technologies in this system will be introduced in detail and its future development trend will be presented.
