Abstract:

The posture of the shield machine and the deformation of the ground can be brought under effective control by means of fuzzy control technology on basis of export experiences. In the paper, the basic principles, control characteristics and study in China and abroad of fuzzy control technology are presented. The stateofart of the application of shield tunneling and the development forecasting are presented in terms of risk assessment, ground displacement and deformation, shield machine posture control and geological condition prediction. The paper can provide references for application of fuzzy control technology in shield tunneling in the future.

Key words: shield machine, fuzzy control technology, risk assessment, posture control, judgment of geological conditions
