| Abstract | This thesis presents the results of an investigation of the
anisotropy of the strength characteristics of Weathered and Soft Bangkok Clay at Rangsit. Ten-inch diameter undisturbed specimens of the Bangkok clay from depths of 2 m, 5 m and 7 m were obtained.
Specimens from the above depths with their vertical axis parallel and perpendicular to the in-situ direction of the major principal consolidation stress were tested undrained in the laboratory after anisotropic consolidation. The anisotropically consolidated undrained test results show
that the Bangkok Clay from the three depths investigated is anisotropic with respect to the strength parameters, the pore ·pressure parameter A at failure and the strain at failure. The combined effect of the inherent or intrinsic anisotropy and of the anisotropy of the stress system acting on the soil in the ground (stress anisotropy) on the above strength characteristics were investigated in this research.
The test results show that the angle of shearing resistance i
was different for the horizontal and vertical samples but this
difference was not very significant in producing the strength anisotropy. The difference in the undrained strength was found to be mainly due to the difference in pore pressures developed in the two
types of samples. |
