Some anisotropic properties of Bangkok Clay are investigated in the laboratory using advanced triaxial apparatus and in the field by self-boring pressuremeter. The triaxial apparatus incorporates local axial & radial strain measurement systems and bender element system. Isotropically consolidated undrained triaxial compression tests are performed on both vertically- and horizontally-cut undisturbed specimens. The anisotropic characteristics of interest are (i) deformation during isotropic consolidation, (ii) small-strain shear modulus, and (iii) modulus during undrained compression shearing. The observed behaviors are compared with other published data from bender element, triaxial, and seismic cone penetration tests. The anisotropic characteristics of Bangkok Clay, which is lightly-overconsolidated clay, are compared with those of London Clay, which is heavily-overconsolidated clay, and some discussions are addressed.
