Abstract:

In the recent shield tunnelling, various requirements are sing led out as targets to overcome for the purpose of meeting the varied social needs; as such requirements, there are lengthening of tunnels, boring at deeper levels, construction of tunnels of larger section, etc. But, for solving these problems, the works management is assumed to become more and more difficult. Having taken sufficient account of the background, development of an automatic control system of the shield tunnelling machine was started setting up the target of labour saving and ensuring of higher work quality.This system is composed of two sub-systems; one is the automatic survey system which features measuring continuously the position and direction of the shield machine referring to the planned tunnelling route, and the other is a computerized direction control system which maintains the shield machine in an appropriate position or attitude in relation to the planned tunnelling route.
