Abstract: Further analyses are performed on the statistical penetration meso-model proposed by authors in part one. Firstly, method for calculating the macroscopic permeability using statistical penetration meso-model is discussed. Then in order to analyze the evolution of permeability in the process of rock failure, anisotropic damage model is introduced to perform the mechanical analysis, and the coupling analysis method using statistical penetration meso-model and anisotropic damage model is also discussed. Finally, permeability variation of Lac du Bonnet granite is analyzed using the methods above, and the theoretical results by statistical penetration meso-model perfectly agree with that measured in situ before rock cracks fully linking up.

Key words: rock crack propagation, statistical penetration meso-model, anisotropic damage model, case analysis
