SUMMARY OR ABSTRACT
Text of Note
"This book describes the stage by stage development of a new method for predicting the penetration rate (PR) and the advance rate (AR) for tunnel boring machine. It is based on an expanded version of the Q-value, termed Q[subscript TBM]. Some 145 TBM tunnels totalling about 1000 km in length were analysed. As a result some simple formulae are developed, to estimate PR and AR from the Q[subscript TBM] value, or to back-calculate Q[subscript TBM] from performance data. Logging methods, empirical TBM tunnel support design, and numerical verification of support are also treated in this slim but practical book on TBM tunnelling." "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 will be useful for geologists, engineering geologists and rock mechanics engineers, civil engineers and mining engineers with a professional interest in TBM tunnelling."--BOOK JACKET.
