Abstract When subjected to continuous dry-wet cycles, rock slopes experience significant disturbances due to water-rock interactions, which lead to dissolution and weathering that can trigger landslide disasters. To investigate the microstructural deterioration and dissolution mechanisms of rock under these conditions, basalt was chosen as the research subject. Experiments were conducted under dry-wet cycles in solutions with varying pH values of 2, 4, 7, 9, and 11. Uniaxial compressive tests, scanning electron microscopy (SEM), and other analytical methods were employed to assess the uniaxial compressive strength and microstructural deterioration of basalt across different pH values and dry-wet cycle conditions. The migration behaviors of key chemical elements within the solutions were analyzed by evaluating their chemical compositions. Based on the dissolution kinetics of basalt, the study explored the microstructural deterioration process and the dissolution mechanisms of water-rock reactions in both non-equilibrium and equilibrium states. The results indicated that, across the various solutions, an increase in dry-wet cycles resulted in a decrease in the uniaxial compressive strength of the rocks and an increase in the proportion of internal microscopic defects. The water-rock reactions in both acidic and alkaline environments transitioned from a non-equilibrium state to an equilibrium state, while those in neutral conditions remained in a non-equilibrium state throughout. Furthermore, the reaction processes in non-equilibrium states across different pH solutions exhibited similar characteristics. The sequence of chemical element release during non-equilibrium water-rock reactions was observed as follows: Ca, Si, and Al, with the concentration of Si increasing as Al substitution intensified. The deterioration of the basalt microstructure was primarily influenced by the release of Si; greater Si release correlated with more severe dissolution of the rock’s internal skeleton. Overall, basalt exhibited the most significant deterioration effects in acidic environments, followed by neutral and alkaline conditions. These findings provide a scientific basis for evaluating the stability of basalt slopes and for understanding the developmental processes of slope-related disasters.
