IMPORTANCE OF INHOMOGENEITY IN ROCK FRACTURING DEDUCED FROM DISTINCT ELEMENT SIMULATION AND IN-SITU DIRECT SHEAR TEST

摘要：

Inhomogeneity is the important nature of rock fracturing including a rock burst. In this paper, the fact that inhomogeneity plays an important role in rock fracturing is elucidated by simulation of uniaxial compression test using our own code of the DEM (Distinct Element Method) and by comparison between AE (Acoustic Emission) source distribution and fracture plane observation of an in-situ direct shear test conducted in a survey tunnel for an underground powerhouse.
