Notes:
Biaxial compression model tests on rockmass containing intermittent joints under planestress condition were carried out in this study, where the laser speckle photo technique was used formeasuring the displacement field. The results obtained have indicated that the laser speckle methodwas effective and the measuring value was about 14% less than the measuring value of dial gauges.Based on the displacement field and the principal stress field which were measured by laser specklephoto technique, dial gauges and strain gauges, the angle of wing incipient crack, the evolution ofstress field at the joint tip and the path of crack extension were deeply studied. The deformation andfailure characteristics, including the fracture mechanism of rockmass, were also analyzed in thisstudy
