• 10.4 Computation Section
• This book focuses on the fundamentals of rock mechanics as a basis for the safe and economical design and construction of tunnels, dam foundations and slopes in jointed and anisotropic rock. It is divided into four main parts:- Fundamentals and models- Analysis and design methods- Exploration, testing and monitoring- Applications and case histories.The rock mechanical models presented account for the influence of discontinuities on the stress-strain behavior and the permeability of jointed rock masses.
