Abstract When disturbed by blast impacts，the high-stress deep surrounding rock joints tend to induce instability failure. To investigate the disturbance shear instability characteristics of rock joints in the neighborhood of strength limit，a series of disturbance shear tests under different initial stresses，disturbance peaks and disturbance frequencies were carried out on symmetrical regular dentate rock joints. The deformation and energy evolution laws of rock joints in the process of disturbance instability were also analyzed. Test results show that the disturbance instability displacement of same rock joints is close to that under quasi-static loading and the cumulative curve of irreversible deformation presents in three stages. Instability displacement of rock joints is controlled by the initial stress state，and the instability is more likely to occur under high initial stress，high disturbance peak and low disturbance frequency. The loading energy and unloading recoverable energy show the “two-way deviation” feature during the deformation process.

Key words： rock mechanics pre-stressed joints low frequency disturbance strength limit neighbourhood irreversible deformation energy evolution
