Determining OCR in Clays from Laboratory Strength
Publication: Journal of Geotechnical Engineering
Volume 114, Issue 1
Abstract
The results of triaxial or simple shear tests may be used to estimate the in situ overconsolidation ratio of clays using a SHANSEP database. A compilation of OCRs and normalized strengths from 116 different clays is presented to discern separate trends for isotropic and anisotropic triaxial compression, extension, and direct simple shear conditions. The method may be used to provide an independent estimate of OCR in clays or supplement the results of consolidation testing. It is observed that natural clays and artificially prepared clays exhibit distinctly different relationships. An example application involving a sensitive sandy clay deposit is used to illustrate the procedure.
