ABSTRACT: This paper is based on the lecture with this title that was given at the Aveiro Course on Geotechnical Risk in Tunnels in 2004. The present subject matter: fault zones and TBM, is richly illustrated with case record figures and pictures, mostly from the personal experiences of the author. The following main topics are covered:
Fault zone experiences in TBM tunnels in Italy, Greece, Kashmir, Hong Kong and Taiwan.
Fault zone cases in the Qtbm data base.
Attempts to be prepared using seismic and core logging and the Qtbm prognosis model.
