Detailed analysis of acoustic emission activity during catastrophic fracture of faults in rock
Xinglin Lei,Koji Masuda,Osamu Nishizawa,Laurence Jouniaux,Liqiang Liu,Wentao Ma,Takashi Satoh,Kinichiro Kusunose +7 more
TL;DR: In this paper, a detailed time-space distribution of acoustic emission (AE) events during the catastrophic fracture of rock samples containing a preexisting joint or potential fracture plane is obtained under triaxial compression using a high-speed 32-channel waveform recording system, and the results are discussed with respect to the prediction and characterization of catastrophic fault failure.
Journal ArticleDOI
A laboratory acoustic emission experiment and numerical simulation of rock fracture driven by a high-pressure fluid source
TL;DR: In this article, the authors carried out rock fracture tests using granite under a confining pressure of 80 MPa with fluid injection in the laboratory and tested a number of numerical models using the FLAC3D modeling software to find the best model to represent the experimental results.
Journal ArticleDOI
Comparison of the microfracture localization in granite between fracturation and slip of a preexisting macroscopic healed joint by acoustic emission measurements
Laurence Jouinaux,Koji Masuda,Xinglin Lei,Osamu Nishizawa,Kinichiro Kusunose,Liqiang Liu,Wentao Ma +6 more
TL;DR: In this article, the authors performed experiments of fracturation and slip of a preexisting macroscopic healed joint under triaxial deformation on granite from Mayet de Montagne (France).
Journal ArticleDOI
Seismic b-Value for Foreshock AE Events Preceding Repeated Stick-Slips of Pre-Cut Faults in Granite
TL;DR: In this article, the b-values for acoustic emission (AE) events during stick-slip cycles of pre-cut faults in granite under triaxial compression (confining pressure: 40 MPa) are investigated.
Book ChapterDOI
Fracturing Behaviors of Unfavorably Oriented Faults Investigated Using an Acoustic Emission Monitor
TL;DR: In this paper, the authors investigated the stick-slip behavior of precut faults having different angles to the greatest principal stress in granite rock samples using an acoustic emission (AE) technique under well-controlled laboratory conditions.
