Singh B., Goel R.K. Tunnelling in Weak Rocks

Elsevier Ltd., 2006. – 489 p.The basic approach in the design of underground support system has been an empirical approach based on rock mass classification. This approach was the subject of the authors’ first book, Rock Mass Classification – A Practical Approach in Civil Engineering (1999), which has been enjoyed by the experts all over the world. Lately, however, a growing need for reliable software packages to aid engineering control of landslide and tunneling hazards has inspired the writing of the next book on Software for Engineering Control of Landslide and Tunnelling Hazards based on the use of a rational approach to check the empirical predictions to be sure of the solution.
The instant liking and success of these two books further boosted our morale and we have written this book on Tunnelling in Weak Rocks, which is based on intensive field-oriented research work and experience. It is expected that the book will generate more confidence and interest among civil and mining design and construction engineers, geologists, geophysicists, managers, planners, researchers and students. The set of three complementary books that we have produced has been possible due to God’s grace, team-work and worldwide acceptance and moral support.
Emphasis is given to the practical-construction solution of tunnelling hazard control rather than any rigorous analytical/numerical methods. Practical knowledge of the engineering behavior of rock masses, discontinuities, the time-tested classification approach, tunnelling hazards, and simple analytical methods are also offered to add to the understanding of realistic actual construction approach. We have been blessed by modern tunnelling machines and shielded TBM with automatic support system to bore rapidly through soils, boulders and weak rocks, etc. By the grace of God, the modern tunnel engineers have tremendous confidence now. This book also tries to integrate the happy experience of tunnel engineers, managers, reputed field researchers and famous site engineering geologists from all over the world. This book may help in on-spot-decisions during tunnelling.
Himalaya is a vast region, an amazingly beautiful creation which possesses extensive rejuvenating life support system. It is also one of the best field laboratories for learning rock mechanics, tunnelling, engineering geology and geohazards. The research experience gained in Himalaya is precious to the whole world.Series PrefaceApplication of geophysics in tunnelling and site survey activities
