COMPRESSION AND EXTENSION OF K SUB ZERO NORMALLY CONSOLIDATED KAOLIN CLAY

Theories for soil deformation and strength have generally been developed from tests on isotropically consolidated samples. However, evidence from tests on anisotropically consolidated reconstituted soils and natural soils suggests that there are major differences between the behavior of one-dimensionally (K sub zero) and isotropically consolidated soils. This paper describes a series of triaxial tests carried out in microcomputer controlled stess path equipment to investigate the strength and the state boundary surface for one-dimensionally normally consolidated kaolin clay. These tests comprise a variety of stress and strain controlled loading paths including drained, constant rho', and undrained test in compression and extension, many of which were not available previously in conventional triaxial equipment. The tests show that both the stength and stress-strain behavior were significantly effected by a one-dimensional consolidation stress history.
