To establish a model that can describe the damage evolution characteristics of rocks under loading, a quantitative relationship between the damage element caused by the expansion of internal micro cracks and the overall damage of the rock is constructed based on the Weibull two-parameter model.

The model validity is verified through triaxial test results of rock under different confining pressures.
