Descriptions
The aim of the present study is to investigate the deformation characteristics of sand subjected to drained cyclic loading. The following major conclusions have been obtained: (1) The stress-dilatancy relationship is recognized to have no effect of the confining pressure in spite of the number of cycles. (2) Although the volumetric strain accumulated for first loading decreases with the increasing over consolidation ratio (OCR), the influence seems to be disappeared with the increasing number of cycles. (3) The anisotropically consolidated sample occurs the volumetric strain larger than the isotropically consolidated one, especially during first unloading.
