Effect of layering characteristics on compressive mechanical properties and damage mechanisms of rocks: Experiments and models.

The investigation of layered rock mechanical properties is important for rock stability analysis. To examine the effects of layer inclination angle (LIA) and layer thickness (LT) on the compressive mechanical properties and damage mechanism of layered rock, this paper proposes a new method of preparing layered rock specimens using similar materials and conducting uniaxial compression tests. At the same time, PFC2D numerical analysis software is used to establish the discrete element numerical model of layered rock under uniaxial compression to deepen its microscopic damage mechanism.
