Abstract

Statistical techniques are used to formulate mathematical expressions for the stress-strain response of soil subjected to a uniaxial strain test. A special mold was used to compact 28 soils at three different densities, and uniaxial strain tests were performed on each sample. A parabolic relationship, a hyperbolic equation, and an exponential formulation are used to describe the measured stress-strain response, and the associated coefficients are assumed to be linear functions of the normalized soil parameters. Among these formulations, the exponential equation is most accurate. The relationship between the constrained modulus and the stress level is also described by several equations.
