This book is essentially a manual for the design of tunnels and other underground spaces in soft ground - soil in contrast to rock. It focuses on stability, prediction of ground movements, and structural design of the lining. It shows that the choice of excavation and support methods depends on ground stability, limitation of damage to the existing built environment and health, safety and environmental considerations. The book builds on the basic principles of soil-structure interaction, the three-dimensional effects of construction sequence and the effects of construction on other...
