| Abstract | The anisotropy of first layer Bangkok sand is investigated in this
study. Anisotropic consolidated compression drained tests (CAD) are
conducted in standard triaxial machine to evaluate the effect of induced
anisotropy and inherent anisotropy. To study the anisotropy, undisturbed
and reconstituted specimens are collected in both vertical and horizontal
direction for testing. Air pluviation method is adopted for preparing
reconstituted sand samples.
Based on the results, the effect of induced anisotropy to E5o and
"s 0 is significant as compared to the findings obtained from CID test
(HAYAT, 1986). It is found that ยข', stress-strain behaviour, "so and
E5o indicate the anisotropy of the first layer Bangkok sand and among
them, "so and E50 are the better indicators. A correlation between the
vertical and the horizontal modulus (E50 ) has been worked out for undisturbed samples
Analyses using finite element method are presented in this study to
illustrate the influence of anisotropy of foundation material to the
behaviour of ground deformation . |
