Abstract The experiments were carried out to investigate the failure process of marble which has cracks with infilling materials under uniaxial compression. The influence of the inclination angle of preexisting flaw and the different filling conditions on the failure process of rock were discussed through analyzing the characteristics of deformation evolution with the digital image correlation method(DIC) and scanning electron microscope(SEM). The results show that the change of the inclination angle of fracture affects the position of crack initiation，the crack angle and the strength of rock to some extent，while the improvement of the compressive strength is a result of fillers. Whether the fracture has filling or not，the failure modes of the rock are mostly because of the combination of shearing stress and tensile stress，but the damage patterns are different. On account of the fillings，the primary failure mode of rock is the wing crack macroscopically，and the shear failure is more obvious mesoscopically. When there is no fillings，two dominant failure modes of the wing crack and anti-wing crack are observed macroscopically and the tensile failure is more obvious mesoscopically.

Key words： rock mechanics digital image correlation filled crack different flaw inclination filler failure mechanism
