Abstract : The design and implementation of large-scale testing equipment for liquefaction studies of near surface saturated sands is reported. The test results can be used to determine material properties required for the development of constitutive relationships capable of describing the behavior of saturated sands during dynamic loading. Specimens of saturated Ottawa sand 16.5 cm by 15 cm by 122 cm were tested and measurements of sample pore water pressure and accelerations taken during shaking. Results of the liquefaction tests have shown that, although qualitative agreement is achieved between the results of this program and those obtained in earlier investigations, the onset of liquefaction as measured in this study takes place at much higher stress levels than previously reported.
