Changes in Electrokinetic Coupling Coefficients of Granite under Triaxial Deformation

Figure 7

Normalized stress, permeability, dilatancy, and coupling coefficient versus time. The gray, red, and blue lines indicate the stages A, B, and C, respectively. Three stages which are divided by the beginning of dilatancy (G01 𝑡=27,000s, G02 𝑡=28,650s) and the beginning of permeability increase (G01 𝑡=36,000s, G02 𝑡=34,750s).
