| Abstract | In this investigation conventional consolidated undrained triaxial tests with pore pressure measurements were carried
out on undisturbed samples of stiff Bangkok clay taken from
depths of 28 to 32 ft from the new AIT campus site at Rangsit.
The testing program was divided into three series. The first and second series consisted of testing samples subjected to
anisotropic consolidation (K = 0.8 and K = K = 0.72) while
o in the third series the samples were subjected to isotropic
consolidation (K = 1) prior to shear. Nonhomogeneity of the samples due to fissures was the main reason behind the scatter in some of the test results. It
was found that deviations from normalized stress-strain
behavior at low consolidation pressures indicated that the
stiff Bangkok clay is overconsolidated. The value of the maximum past pressure was independent of the type of consolidation and lay in the range from 60 to 75 Ib/in2
The undrained shear strength as a function of consolidation pressure was found to be higher for the anisotropically
consolidated samples. Moreover, anisotropic consolidation
produced greater values of c and . The maximum obliquity ratio was found to increase by anisotropic consolidation while
the pore pressure parameter, Af, was generally decreased by
anisotropic consolidation as compared to isotropic consolidation. |
