A 1000 km and 145 case record analysis shows how TBM advance rate gradually declines, whether breaking world records like 16 km in one year, or when stuck in a fault zone with|About the Author||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-sys

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, Q_TBM. The author analyzes 145 TBM tunnels that total 1,000km in length. He then develops simple formulae to estimate PR and AR from the Q_TBM value and to back-calculate Q_TBM from performance...
