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.
