A Numerical Study of Wave Propagation and Cracking Processes in Rock-Like Material under Seismic Loading Based on the Bonded-Particle Model Approach
文献摘要：
An earthquake is usually followed by a considerable number of aftershocks that play a significant role in earthquake-induced landslides.During the aftershock,the cracking process in rocks becomes more com-plex because of the formation of faults.In order to investigate the effects of seismic loading on the crack-ing processes in a specimen containing a single flaw,a numerical approach based on the bonded-particle model(BPM)was adopted to study the seismic loading applied in two orthogonal directions.The results reveal that no transmission and reflection phenomena were observable in the small specimens(76 mm x 152 mm)because they were considerably smaller than the wavelength of the P-wave.Furthermore,under seismic loading,the induced crack was solely tensile in nature.Repeated axial seis-mic loading did not induce crack propagation after the first axial seismic loading.Cracks began to prop-agate only when the seismic loading direction was changed from axial to lateral,and then back to axial,ultimately resulting in the failure of the specimen.
