英文摘要	In this work, we proposed a hydraulic fracturing model for layered rock based on peridynamics and studied the mechanism of hydraulic fracturing in a layered rock mass, i.e., complex propa-gation behaviors at the interface such as crossing, kinking, bifurcation, and arrest. Furthermore, we explored the effects of stress difference, elastic modulus ratio, and interface dip angle on the propagation behavior of hydraulic fractures. We found that the stress difference has an important influence on the propagation of hydraulic fractures in a layered rock mass. When the hydraulic fracture design direction is perpendicular to the direction of the maximum principal stress in a layered rock mass, the fracture network will be induced.
