In this paper, the authors discuss on the application of computer simulation model and “Fracture Mechanics” to describe the failure process of rocks under the compressive load.
Itis well-known that the criterion of the initiation of fracture crack doesnot coincide with the criterion of the propagation of it in compression test. The linear fracture mechanics is applied to interprete the inherent process of compression failure of rocks and the correlation between the initiation and propagation of fracturecracks and the stress-strain diagram.
In order to evaluate the applicability of linear fracture mechanics to the processes ofcompression failure, a computer simulation model is designed. The result of simulation is very similar to the well-known test results on the failure process of uniaxial compression ofrocks. This suggests the applicability of linear fracture mechanics and computer simulation to the analysis of failure processesof rockin compression.
