The invention discloses a rock fracture simulation sample and a preparation method thereof, a rock fracture simulation test apparatus and a rock fracture simulation test method, and belongs to the technical field of rock samples. The rock fracture simulation sample comprises a rock body, a first casing, a second casing, ..., and an N-th casing. The preparation method comprises: preparing a rock sample body, a first casing, a second casing, ...,and an N-th casing; digging a first blind hole, a second blind hole, ..., and an N-th blind hole on the sample body; processing perforation clusters on the body by adopting the inner walls of each blind hole as the starting points; and injecting an adhesive into the ring cavities between each casing and each blind hole to prepare the sample. The rock fracture simulation test apparatus comprises the simulation sample, a fracturing liquid injection device, a fracturing fluid, a fracturing liquid injection pipeline, a plunger device and a valve. The simulation test method is achieved based on the rock fracture simulation test apparatus. According to the present invention, the indoor stimulation on the on-site rock fractured crack can be achieved, and the valuable reference can be provided for the actual work according to the analysis of the simulation test results.
