The paper conducted the uniaxial compression test to white sandstone after heat treatment and analyzed the variation law of peak stress, longitudinal wave velocity, Young's modulus and damage form of white sandstone with temperature,and established the equation between temperature and damage variables of white sandstone.It analyzed the relationship between the damage variable and mechanical parameters. The result shows that after heat treatment, white sandstone shows some self-healing within a range of temperature;the relationship between physical and mechanical parameters and temperature presents quadratic nonlinear law; the heat treatment has little effect on failure mode of white stone;the damage of heat treatment has more effect on physics parameter than that on mechanical parameter.The study results have important value for the construction of rock engineering in the circumstance of high-temperature.
