Abstract

Many different testing apparatus are used to duplicate in laboratory soil samples the stress state generated in situ by earthquakes. A wide diversity of data has been generated and this paper compares the cyclic behavior of soil predicted by cyclic triaxial, simple shear and torsional shear test apparatus. Comparisons are made for drained and undrained samples with and without initial static shear stresses and for both stress and strain controlled tests. Results show that similar volume change, pore pressure build up and stress ratios to cause liquefaction are measured by the different apparatus. In general, triaxial tests predict the largest liquefaction resistance, simple shear the lowest, and torsional shear somewhere in between.
