Abstract

Correlations between cone penetration resistance and liquefaction resistance of sandy soils are examined, based on high quality undisturbed samples obtained by the in situ freezing method. For this purpose, the CPT tests are conducted at six sites where in situ frozen sands with fines contents up to 30 % were sampled and their dynamic properties were determined in the laboratory. The comparison of the CPT data with the soil properties of the in situ frozen samples has shown that: (1) Robertson's soil classification chart performs well for sandy soils in Japan; (2) the CPT qt-value shows a good correlation with elastic shear modulus of the in situ frozen samples; and (3) the liquefaction resistance of the in situ frozen samples is uniquely expressed if the cone penetration resistance is normalized in terms of confining pressure and minimum void ratio.

Correlation between CPT Data and Dynamic Properties of In Situ Frozen Samples

St. Louis, Missouri

Correlations between cone penetration resistance and liquefaction resistance of sandy soils are examined, based on high quality undisturbed samples obtained by the in situ freezing method. For this purpose, the CPT tests are conducted at six sites where in situ frozen sands with fines contents up to 30 % were sampled and their dynamic properties were determined in the laboratory. The comparison of the CPT data with the soil properties of the in situ frozen samples has shown that: (1) Robertson's soil classification chart performs well for sandy soils in Japan; (2) the CPT qt-value shows a good correlation with elastic shear modulus of the in situ frozen samples; and (3) the liquefaction resistance of the in situ frozen samples is uniquely expressed if the cone penetration resistance is normalized in terms of confining pressure and minimum void ratio.
