| Abstract | ||
| The generalization of DARCY’s law in 2.diemnsions has led to equations which describe permeability of the soil as a symmetric tensor of second rank (1, 2). In seepage problems it is common to define the GLOBAL coordinate axis to coincide with the principal directions of the permeability tensor, therefore, the cross product (off – diagonal) components (Kxy , Kyx) of the permeability tensor will be zero. It is therefore the purpose of this research to show the influence of the off- diagonal terms of the permeability tensor on the determined exit gradients behind a vertical sheet pile embedded in an anisotropic homogenous soil of finite depth. Also of interest is the derivation of an equation for the determination of exit gradients obtained from coordinate transformations of composite function. | ||
