In complex rock engineering, understanding the stress state and determining stability and damage evolution are necessary.
To more accurately provide a theoretical basis for judging the stress state of bedrock in engineering, this study experimentally addressed the damage evolution of sandstone under loading and unloading conditions.
A theoretical relationship between rock resistivity and porosity was obtained according to the Archie formula, which allowed the derivation of the sandstone damage variable expression.
Then, sandstone rock samples were used for experimental evaluation, and the feasibility of the theoretically determined damage variable was verified.
Finally, through theoretical and experimental comparison analysis, we developed a correlative damage model for sandstone under uniaxial loading and unloading.
The results show that the damage variable varies linearly with strain.
The proposed correlative equation describes this behavior accurately for loading and unloading conditions.
Based on the results of this study, the correlative damage model of sandstone under cyclic loading and unloading conditions can be further improved to be a complete constitutive damage model.
