Modern Trends in Tunnelling and Blast Design by J. Johansen
A review of modern blasting techniques used in tunnelling, chamber excavations and lake-tap blasting. The scope of this book includes geological implications, cut design and smooth blasting techniques in addition to chamber blasting. This book also includes detailed examples outlining the design issues and techniques used in blasting lake-tap plugs for hydroelectric projects. It is designed as a reference book and companion to courses in tunnel blasting techniques.

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.

The basic principles of Yield Line theory are explained and its application as a versatile method for the design and assessment of reinforced concrete slabs is demonstrated. Theory is followed by practical examples and the accompanying commentary gives insights into the years of experience brought to bear by the main author, Gerard Kennedy.
It commits to paper a practical approach to the use of Yield Line for the design of concrete slabs. It gives guidance on how to tackle less simple problems, such as the design of flat slabs,
rafts, refurbishment and slab-beam systems.
