In this Volume 4 of the WBI-Print series, Stability Analysis for Tunnels, the author presents fundamentals of stability analysis gained through 25 years experience with the development and application of numerical analysis procedures and computer programs for tunnel design. The book focuses on a range of topics including; stability of tunnels in jointed rock, design of tunnels in swelling rock, stability of openings in salt rock, ground-water lowering due to tunnel excavation, stability of working face during shield tunnelling with compressed air, tunnelling in saturated cohesive soils, consolidation of cohesive soils due to tunnelling.
