Features: This book establishes a mechanical model to describe the coupled effects of fluid flow-stress-damage in rock media. It analyzes and discusses several key issues, including the evolution of permeability induced by stress and its resulting damage, the influence of nonlinear permeability distribution on stress-strain, peak strength, and failure patterns, and the impact of pore and fracture structure distribution on the fluid flow-stress coupling mechanism, thereby studying the complexity of the permeability-stress-damage coupling mechanism in rocks. Combined with examples such as the fluid flow failure of surrounding rock caused by subway tunnel excavation and the sudden water inflow from the floor caused by confined water action, the book introduces the failure and instability mechanisms of engineering rock masses under the coupled effects of fluid flow and pressure. This book is not only a reference for professionals engaged in geotechnical engineering production, research, and teaching in departments such as geology, water conservancy, transportation, mining, and national defense, but can also serve as a teaching reference for postgraduate students in engineering geology, water conservancy engineering, mining engineering, and geotechnical engineering. The RFPA2D-Flow software system provided in this book also offers a valuable experimental tool for teaching and learning basic properties of rock mechanics and hydrology, which can be applied in universities and research institutions.
