Abstract:Coarse-grained soil particles will be obviously broken under high stress, and particle breakage is the main reason for the compression of samples. The compressibility λ in e-logσ curve is closely related to the degree of particle breakage. In this paper, a term of surface energy caused by particle breakage is added to the energy conservation equation. The variation of surface area per unit volume of sample is described by fractal dimension, and then the relationship between fractal dimension and vertical stres… Show more
