Abstract
In an attempt to study microcracks development, coordination number, volumetric strain, and permeability evolution of sandstone, the hydromechanical coupling mesoscopic simulation was carried out using Particle Flow Code 2D software based on experimental results of permeability evolution in the complete stress–strain process obtained via triaxial compression tests. A numerical model conforming to the laboratory experiments was established, and the critical mesoscopic mechanism was analyzed. The studied results have included big data as one of the examples for the application of Industrial Internet of Things. In particular, the following were investigated in details in this paper: the stress–strain curves, the distribution of pore pressure, the characteristics of crack growth, the coordination number, the volumetric strain, and the evolution characteristics of permeability under hydromechanical coupling conditions. A discussion is also provided, based on the numerical simulation and analysis of hydromechanical coupling effect, on the synergistic action among changes of mesoscopic structure, accumulated damage, and permeability evolution of the sandstone under hydro-mechanical coupling.
