Correlation between Strengths and Penetration Resistances for Gravelly Soils
Soils and Foundations, 1993 High-quality undisturbed gravel samples, 30 cm in diameter and 60 cm high, are obtained by the in-situ freezing method at four sites. Both the undrained cyclic shear strength and drained shear strength of these samples are measured by using a large scale triaxial test apparatus.
