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 sigma sub z versus epsilon sub z 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. Author
