The current technological and practical achievements
in shield tunneling construction are evaluated with particular focus on shield
automatic driving. Also, the developments in theoretical research are
summarized based on rock and soil identification, shield attitude control, and
ground settlement control. Thereafter, a hierarchical automatic driving control
system and a control method for data, mechanism, and experience fusion are
proposed. A case study is conducted on the ZhiYu shield automatic excavation
and control system. The exploration results of the shield automatic driving
technology including the control link design, the model structure of the core
control algorithm for attitude and settlement, and the application of the
system in actual engineering practice are explored. Finally, the challenges in
shield automatic driving technology are discussed and the future development
trends are predicted.
