Study on the Mechanical Properties and Degradation Mechanisms of Damaged Rock Under the Influence of Liquid Saturation by Bowen Wu, Jucai Chang, Jianbiao Bai, Chao Qi, Dingchao Chen

“…To investigate the degradation mechanisms of the surrounding rock in abandoned mine roadways used for oil storage, this study combined uniaxial compression tests with digital image correlation (DIC), scanning electron microscopy (SEM), and other techniques to analyze the evolution of the rock mechanical properties under the coupled effects of oil–water soaking and initial damage. The results indicate that oil–water soaking induces the loss of silicon elements and the deterioration of microstructure, leading to surface peeling, crack propagation, and increased porosity of the sample. …”
