The invention discloses a rock fracturing simulation test specimen with crack, a preparation method for the rock fracturing simulation test specimen, a simulation test apparatus and a simulation test method, and belongs to the technical field of rock simulation tests. The rock fracturing simulation test specimen comprises a rock test specimen body, a fracturing fluid injection tube and a pouring material. The pouring material covers the rock test specimen body so that the formed rock fracturing simulation test specimen with the crack is integrally in the shape of a cuboid, a blind hole starts to be formed in an end point of the cuboid and is terminated at the rock test specimen body, the fracturing fluid injection tube is fixedly connected onto the wall of the blind hole, an accommodating space is reserved between the bottommost end of the fracturing fluid injection tube and the bottommost end of the blind hole, and a plurality of spray holes start to be formed in the wall of the blind hole and extend towards the rock test specimen body. The rock fracturing simulation test specimen is applied to the simulation test apparatus, and the simulation test method is based on the simulation test apparatus. The rock fracturing simulation test specimen, the preparation method, the simulation test apparatus and the simulation test method have the advantages that crack fracturing physical simulation can be carried out on rock masses of shale gas reservoirs by the aid of the rock fracturing simulation test specimen, the simulation test apparatus and the simulation test method, and the rock fracturing simulation test specimen, the simulation test apparatus and the simulation test method also can be used for rock masses of other tight reservoirs and accordingly are high in applicability.
