Abstract: Rocks were typical inhomogeneous brittle materials with abundant various deficiencies inside and will generate plenty of acoustic emission signals during damage process under loading.On the condition of uniaxial loading in laboratory,fracture mechanism and behavior characteristic during failure process of rock sample with different number of holes were studied by apply sound emission monitoring system and stress analyzing software(the 3D failure process analytic system of rock samples,RFPA3D).

Key words: Rock samples with holes, Fracture characteristics, Sound emission
