Hardrock Tunnel Boring Machines

This book covers all aspects of TBM tunnelling: boring, driving, muck clearance, support, rock classification for mechanical tunnelling and also contract considerations.
A multitude of example projects clarify the current state of the technology, and problem cases are discussed along with innovative solutions and special equipment.
The close collaboration of expert authors has produced a work of interest to the experienced tunnel builder just as much as the newcomer to the field.
