Tbm Tunneling in Jointed and Faulted Rock

This practical book on TBM tunnelling presents a methodology for predicting the penetration rate (PR) and the advance rate (AR) for tunnel boring machines. Some 145 TBM tunnels, totalling 1000 km in length, were analyzed and simple formulae have been extrapolated from the results to estimate PR and AR from the Qtbm value, or to back-calculate Qtbm from performance data. Logging methods, empirical TBM tunnel support design, and numerical verification of support are also treated. This book is a useful source of reference for consultants, contractors and owners of TBM tunnels, and for those involved with feasibility studies, machine and support design and follow-up of tunnel progress. Among the geotechnical community, the book is valuable for geologists, engineering geologists and rock mechanics engineers, civil engineers and mining engineers with a professional interest in TBM tunnelling.Barton, N.
