摘要

This paper first describes the extended use of fall cone (British Standards cone penetrometer) to determine simultaneously the liquid and plastic limits of soils, following the procedure proposed by the author (Shimobe & Miyamori 1996). Next to substantiate the water content - strength relationship of soils, the undisturbed and remoulded undrained shear strengths for various soils have been determined each with the laboratory vane and fall cone tests over a wider water content range. Using the liquidity index obtained from such fall cone tests, a simple model introducing the effect of sensitivity can be established to define the liquidity index - cone penetration relations for undisturbed and remoulded soils. The relationships between the undrained strength and liquidity index of these soils with the contours of sensitivity also are suggested and the undrained strength - cone penetration correlation derived by Hansbo (1957) is re-examined.
