Abstract

This study was performed to evaluate the critical state parameter of crushable Jeju sand and to suggest the relationship between the state parameter and cone resistance of Jeju sand. It is observed from a drained triaxial test that Jeju sand mainly shows contractive behavior due to high void ratio and large compressibility. Although strain localization is not evident, the particle crushing results in a lower void ratio than the critical state void ratio of some Jeju specimens. Critical state parameters of Jeju sand are similar to those of calcareous sands, but significantly larger than those of common sands. The relationship between the normalized cone resistance and state parameter of Jeju sand significantly differs from that of other materials, and this relation appears to be affected by the stress level. This is because the variation of stress level affects the state parameter of Jeju sand more significantly than that of common sand due to the high compressibility of Jeju sand.
