Influence of cyclic impacts on the dynamic viscosity of rocks under high water pressure and stress conditions
Abstract Deep rock engineering often operates in water-rich environments, resulting in the coupled effects of high water pressure, high stress, and cyclic dynamic loads on rock masses. Under these conditions, deep rock masses exhibit pronounced viscous behavior. The dynamic viscosity factor (DVF) is...

| description | Abstract Deep rock engineering often operates in water-rich environments, resulting in the coupled effects of high water pressure, high stress, and cyclic dynamic loads on rock masses. Under these conditions, deep rock masses exhibit pronounced viscous behavior. The dynamic viscosity factor (DVF) is a significant parameter for characterizing the viscous behavior of rocks. Initially, cyclic impact tests are performed on rocks using a self-created test equipment. Subsequently, an analysis is conducted for the evolution of DVFs in relation to the cyclic impact time and dynamic deformation modulus. Test results show that DVFs decreases exponentially with increasingly cyclic impact times, which is abbreviated to as DVF deterioration. Axial static stresses are shown to promote the occurrence of static damage within the rock. This process is found to accelerate the deterioration rate of DVFs. water pressure has been shown to boost the rock’s resistance to impacts. The effect on DVFs is dominated by enhancement effects, and thus the deterioration rate of DVFs is slowed down. As cyclic impact times rise, the deformation properties of rocks are gradually changed from elastic to viscous behavior. The findings of this research provide valuable insights for addressing the deep rock engineering disasters, such as water inrush, in the water-rich environment. |
