Abstract
To investigate the acoustic emission characteristic of rock under different compressive loading rates, a numerical approach using the bonded-particle model (BPM) is adopted in the present study. It reveals that under uniaxial compressive test, the physical mechanism and distribution of AE events recorded by the BPM are generally consistent with the phenomena observed from the laboratory experiments. The total crack number, tensile crack number, shear crack number and AE event number increase as the loading rate increases. The increase of loading rates from 0.005m/s to 0.6m/s in the BPM does not have obvious influence on the distribution of AE events.
