Rock fracturing testing device under heat-fluid-solid coupling effect

The invention belongs to the technical field of rock mechanics and fracturing, and discloses a rock fracturing testing device under a heat-fluid-solid coupling effect, which comprises a triaxial pressure chamber, a servo pressurizing unit, a hydraulic pressurizing unit and a temperature control unit, a rock sample is arranged in the triaxial pressure chamber, and a blind hole is formed in the rock sample; the servo pressurizing unit is communicated with the triaxial pressure chamber and is used for applying axial and/or radial pressure to the rock sample; the hydraulic pressurizing unit extends into the blind hole and is used for applying water pressure to the blind hole; the temperature control unit is arranged in the triaxial pressure chamber and used for controlling the temperature of the triaxial pressure chamber. When the rock fracturing test is carried out, the comprehensive effect of the temperature, the water pressure and the stress on the rock is considered, the finally determined rock fracturing par
