摘要：

The influence of crack filling on the mechanical property of jointed rock mass is studied. The brittle jointed rock mass specimens with preset crack are simulated by the similar material. The mechanical properties of specimens are tested by uniaxial compression. The fracture and damage of jointed rock mass are analyzed through the program ABAQUS. The tests and analyses results show that compared with the specimens that there are no filling in the crack, the peak strength of jointed rock specimens which have filled crack slightly increase and its post-peak plasticity is enhanced significantly; the strain energy release rate Gc of jointed rock specimen decreases. The damage factor and the hoop tension stress field area as well as peak are less than those of specimens with non-filled cracks.
