This practical guide describes the stage-by-stage development of a method for predicting the penetration rate (PR) and the advance rate (AR) for tunnel boring machines based on an expanded version of the Q-value, QTBM. The author analyzes 145 TBM tunnels that total 1,000km in length. He then develops simple formulae to estimate PR and AR from the QTBM value and to back-calculate QTBM from performance data. The book quantitatively explains actual advance rates as high as five m/hr for one day or as low as 0.005 m/hr for several months. It also covers logging methods, empirical TBM tunnel support design, and numerical verification of support.

Schweitzer Klassifikation
Nick Barton has over 40 years of international experience in rock engineering, and has been involved in numerous important and iconic tunnel, cavern and rock slope projects. He has developed many tools and methods, such as the widely used Q-system, for rock classification and support selection and the Barton-Bandis constitutive laws for rock joint computer modeling. He currently teaches at the University of Sao Paulo and manages an international consultancy (Nick Barton & Associates, Sao Paulo - Oslo).
Dr. Nick Barton was the 2011 recipient of the distinguished Mueller Award, an award that honours the memory of Professor Leopold Mueller, the founder of the ISRM (International Society of Rock Mechanics), and awarded in recognition of distinguished contributions to the profession of rock mechanics and rock engineering.
