Linear stress-strain equations are generally employed in the solution of soil displacement problems; however, those equations are usually valid for small deformations only. Displacements encountered in soil mechanics problems are often of large magnitudes and therefore a nonlinear stress-strain equation should be used. The derivation of pore pressure equations which are based on nonlinear stress-strain properties are presented herein.
