[P02-10] Evaluation of Compressibility of Geomaterials with Soil Particle Breakage
Keywords:sand, compression, particle breakage, prediction
The large compressibility with particle breakage of Ryukyu limestone sands is predicted by the power rule of logarithm void gradient. It is revealed that the different compressibility from initial void ratio is evaluated in the material constants ξ of the power rule, and the different compressibility from particle strength in the hardening/softening coefficient K0.
