Abstract

Authors measured K0-value in-situ using Self-boring lateral load tester (SBLLT) and Flat-diratometer (DMT). After that, a series of cyclic undrained torsional shear tests under the plane strain condition on anisotropically consolidated condition (K0-condition) has been performed using undisturbed tube sampling to investigate the relation between the liquefaction strength of isotropically consolidated condition (Rlisotropic) and K0-condition (RlK0). The result of these laboratory tests shows that the liquefaction strength defined as 7.5% shear strain in double amplitude of undisturbed silty sand is generally agreement between triaxial and torsional test with isotropically and anisotropically consolidation. However, the cyclic behavior up to liquefaction strength defined as 7.5% shear strain in double amplitude was a greatly difference in stress condition.

Effect of K0 on Liquefaction Strength of Silty Sand

San Diego, California

Authors measured K0-value in-situ using Self-boring lateral load tester (SBLLT) and Flat-diratometer (DMT). After that, a series of cyclic undrained torsional shear tests under the plane strain condition on anisotropically consolidated condition (K0-condition) has been performed using undisturbed tube sampling to investigate the relation between the liquefaction strength of isotropically consolidated condition (Rlisotropic) and K0-condition (RlK0). The result of these laboratory tests shows that the liquefaction strength defined as 7.5% shear strain in double amplitude of undisturbed silty sand is generally agreement between triaxial and torsional test with isotropically and anisotropically consolidation. However, the cyclic behavior up to liquefaction strength defined as 7.5% shear strain in double amplitude was a greatly difference in stress condition.
