Flow characteristics of ftactured rocks
Webence of roughness, fracture geometries, and inertial effects on flow be-haviors in 3D rock fractures. However, the impacts of the mechanical loading on the changes of void spaces and contact, as well as their effects on the flow characteristics in the 3D real rock fractures have not been solved using the N-S equations to the authors’ knowledge. WebOct 1, 2024 · Abstract. The deeply fractured rock mass exists in the environment of in-situ stress and high seepage pressure, and they are prone to seepage-slipping failure. Therefore, it is of excellent engineering value and theoretical significance to study the nonlinear seepage evolution of fractured rock mass under water-rock mass coupling.
