Abstract: A four-layer soil profile consisting of three nonlinear hysteretic layers of limited shear strength over a deep linearly elastic layer has been developed for the In-Cell Incident test area at the WES Big Black Test Site. Recommended constitutive properties consisting of seismic velocity, wet unit weight, uniaxial strain test σ𝘻 versus 𝜖𝘻 curve, yield surface, and a stress path corresponding to the UX stress-strain curve have been developed for each layer. All follow available data closely except the stress paths. The stress paths recorded are based on limited data and judgment since analyses showed serious errors in the stress-path data obtained in this study. These errors demonstrated the importance of improving control of drainage in the WES null test device. This study was limited to the drilling of an undisturbed sample boring at the Big Black Test Site and the conduct and analysis of (A. )dynamic uniaxial strain UX tests, (B.) dynamic triaxial compression TX tests, and (C.) a few static radial stress controlled UX or null tests on specimens from 5-in.-diam fixed-piston soil samples from the top 20 ft of the WES Big Black Test Site.
