A discrete approach for modelling the permeability evolution of granite under triaxial and true-triaxial stress conditions

IOP Conference Series: Earth and Environmental Science
Abstract In deep underground engineering, modelling the seepage characteristics of rock masses under complex stress conditions is crucial for the safe construction and stable operation of a project. The permeability of the rock mass is not only controlled by its internal pore structure but is also closely related to the deformation and ...
