Background
The influence of high temperature on geotechnical media has been an eager leading topic of researchers, such as deep-buried geotechnical engineering, deep-buried disposal of nuclear wastes, and the like. In order to further study the mechanical properties of the rock, the influence of temperature on the mechanical properties of the rock is usually studied through a large number of experiments, and the mechanical properties of the rock, which are shown under different temperature gradients, are analyzed. However, at present, in related experiments for researching the influence of temperature on the mechanical properties of rocks at home and abroad, protection and analysis on the influence of oxidation of rock samples on the properties of the rock samples in the heating and heat preservation processes are hardly considered, and the rocks show different mechanical properties under the influence of factors such as components, water content, pore structures and the like. In order to better simulate a high-temperature oxygen-free environment, control independent variables in an experimental process and ensure the objectivity of a test result, an urgent problem is solved, and at present, no anti-oxidation experimental device for a rock mechanics high-temperature experiment, particularly a uniaxial compression experiment, exists.
