Investigating stress distrubution in the soil via the identification of three parameter anisotropy

There has actually been sufficient number of precious studies, which offers numerical or analytical solution for the stress and displacements in cross-anisotropic media. These studies have mostly evaluated the effect of anisotropic parameters on stresses and displacements. However, these solutions are also capable of performing realistic analyses considering the change that the soil experienced due to loading, compaction etc. For this, realistic anisotropic parameter sets (such as experimentally obtained), reflecting the changes that the soil undergoes, are needed. Therefore, in the content of this study, the possibility of obtaining such data sets were investigated to be able to perform more realistic stress and displacement analyses. Benefiting from three-parametric description of anisotropy, proposed by Graham and Houlsby, new data sets were produced considering the change in wide range of anisotropy that the soil can have. In this context, new sets of dimensionless cross-anisotropic parameters (n, m, and ) were produced by controlling ? parameter ( ), for a given vertical Young?s modulus, . Great experimental effort were spent to obtain anisotropic parameters of Yenice/Tarsus clay and new data sets of anisotropic parameters were then produced. Thus herein, analyses were carried out for elastic homogenous halfspace and the variation of stresses/displacements with type and degree of anisotropy were investigated using those produced anisotropic data sets. Additonally, the stresses/displacements obtained by three-parametric anisotropy were compared with the results obtained by the usual parametric way in which one parameters is changed as the others have typical constant values.Consequently, it was found that all anisotropic parameters are interrelated thus they change accordingly and stresses/displacements are sensitive to both variations in n and m and the order of change is considerable in realistic range in both n and m moduli ratios. Besides, smaller vertical stresses and displacements are evident for the n>1 type of anisotropy while it is larger for n<1 type of anisotropy than the stresses and displacements obtained by usual parametric way.
