Undrained shear strength from cone penetration tests

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Results of unconsolidated-undrained triaxial tests, field vane shear tests and cone penetration tests have been used to develop correlations between undrained shear strength and cone resistance for a soft to medium alluvial clay in the Lopez Canyon area of San Diego. When comparing UU triaxial results with cone resistance, the average cone factor was 11 with a standard deviation of 1.5. When comparing corrected field vane shear strength with cone resistance, the average cone factor was 13 with a standard deviation of 1.0. The difference in the measured values of shear strength is most likely due to soil anisotropy and/or differences between triaxial and vane shear tests. For design, an average cone factor of 12 is recommended for alluvial clay with similar characteristics as that found in Lopez Canyon.
