Abstract

A method is suggested to determine piecewise linear, stress-dependent relationships for the modulus and Poisson's ratio of soils. The method is based on linear elasticity and conditions associated with conventional triaxial tests at different states of stress. The tangent modulus at a given stress level is shown to be the slope of the axial stress-axial strain curve at that stress level, and the value of Poisson's ratio is evaluated by use of theoretical considerations and a simple graphical construction. This method of interpretation is applied to experimental data from two natural soils used in an actual full-scale field installation of buried concrete pipe.
