IN-SITU STRENGTH CHARACTERISTICS OF SOFT CLAYS

The change in effective stress condition resulting from sampling of saturated clays is examined. A link, in terms of Hvorslev strength parameters is established between the perfectly undisturbed sample strength and the in-situ strength. The theoretical analysis and the supporting experimental data indicate that for normally consolidated saturated sensitive clays, the in-situ strength and pore-pressure coefficient are significantly different from those measured on even perfectly undisturbed samples in unconsolidated-undrained triaxial compression tests. An expression is proposed for the evaluation of the in-situ strength of normally consolidated saturated clays in terms of the soil strength parameters and the pore-water pressure coefficient in-situ.
