| Abstract | Yielding of Soft Bangkok Clay at states below and on the State Boundary Surface has been
studied under compression loading conditions. The experimental programme includes isotropic
consolidation and swelling tests with conventional undrained and p-constant tests at different
overconsolidation ratio within the State Boundary Smface. Based upon the plastic volumetric yielding as observed in the experiments canfod out, the
region within the State Boundary Surface has been divided into four zones. In zone one, the
volumetric strain is purely elastic and is close to the p-axis. In zone two, plastic volumetric strain
is compressive, whereas in zone three both compressive and dilational (expansive) plastic volumetric strains are developed. In zone four the plastic volumetric strain is purely dilational in
nature.
The plastic strain increment ratio on a particular stress ratio line was found to depend on
the normalized mean normal stress and was associated with yielding behavior of clay in side the
State Boundary Surface.
On the basis ofdistortional strains noted in conventional undrained and p-constant drained
test the analysis within the State Boundary Smface can be considered as a linear one irrespective
of drainage condition by adopting a suitable factor of safety. The experimental results from this investigation will provide useful contribution toward
the formulation of theories dealing with "associated and non-associated flow rule" as generally
envisaged in the elasto-plastic behavior of soil |
