Energy Characteristics of Brittle Rock in Failure Process

Abstract:

Energy transformation in rock failure process is a complicate process, especially in the high geostress conditions. First from the point of energy, analysis and study on the rock deformation and failure process under uniaxial compression and triaxial compression condition. Based on the test results, the deformation failure characteristics and its energy in triaxial compression are analyzed. Reveal the energy dissipation and energy release characteristics in the process, and found the internal causes is stored elastic in rock mass unit can release suddenly and cause rock damaged. Especially in the high geo-stress condition, the compressed engineering rock mass are often faced with the risk of unloading damage. After add anchor, the mechanics performance of specimen after peak period is significantly improved, and can absorb more of the release of strain energy, which is helpful for maintaining the overall stability of surrounding rock.
