Method, device, medium and equipment for simulating mechanical behavior of orthogonal jointed rock mass

The invention provides a method, a device, a medium and equipment for simulating mechanical behaviors of orthogonal jointed rock, and belongs to the technical field of numerical simulation of rock mechanics. The method comprises the following steps: acquiring a geometric model of a rock engineering structure to be simulated; block cutting is conducted, the distance between adjacent joints is made to be m-level scale, discontinuous deformation analysis blocks are generated, and contact boundaries of the discontinuous deformation analysis blocks are formed; carrying out modeling treatment to obtain the orthogonal joints contained in the discontinuous deformation analysis block, so that the orthogonal joints contained in the discontinuous deformation analysis block are in a cm-level scale; performing mathematical simulation to obtain a stiffness matrix of the discontinuous deformation analysis block; and solving and analyzing to obtain mechanical behavior parameters corresponding to the discontinuous deformation
