Disclosed is a method for triaxial pressurized freezing for making ice, the method comprising the four steps of assembling an apparatus, obtaining temperature control parameters, carrying out pressurized freezing, and carrying out a mechanical test. The apparatus comprises a loading system, a temperature control system, and a temperature measuring system. The loading system comprises a loading frame, a pressure volume controller, a triaxial cell, and an oil injection pump. The apparatus is combined with the method for making ice to realize a controllable sample stress field and a controllable sample temperature field in the whole process of pressurization, freezing, and testing, so as to manufacture a sample meeting the specification of a triaxial test under the conditions of different freezing pressures and freezing speeds. The method is adapted to researching the influence of freezing pressure and freezing speed on ice mechanical characteristics, has high experiment efficiency, and does not involve toxic or
