Features: This book systematically elaborates on the current state of rock mechanics research and the principles and methods of unloading rock mechanics. It provides a detailed introduction to the research content of unloading rock mechanics, discusses systematic engineering problems in rock mechanics, the engineering characteristics of unloading rock masses and their research methods, the strength theory of tensile-shear and compressive-shear fractures in jointed rock masses, the anisotropic properties of unloading rock masses, the size effect of unloading rock masses, the rheological properties of rocks, the numerical simulation methods for macroscopic mechanical parameters of unloading rock masses, and the application of BP neural networks, among others. Based on the experimental results of triaxial strength of unloading rock masses, it discusses their failure criteria and proposes the basic methods for finite element analysis of unloading rock masses. Combining some characteristics of unloading rock masses, it outlines the fundamental ideas for strengthening unloading rock masses. Finally, it presents engineering application examples. This book is suitable for teachers, engineering and technical personnel, graduate students, and senior undergraduate students in fields such as water conservancy and hydropower, civil engineering and architecture, mining and railway, and transportation and metallurgy for reference.
