Liquefaction of loose, saturated sands may be caused by cyclic or static (monotonically increasing) undrained loading. Most previous studies of static liquefaction behavior have emphasized liquefaction susceptibility and the behavior of liquefied soils. Samples were drained in the field and then carefully transported to the laboratory. Stress-controlled, constant height, cyclic simple shear tests were then conducted in order to determine the cyclic stress ratios causing liquefaction using a new cyclic simple shear device designed by Dr Michael Riemer of the University of California, Berkeley. The potential for static and cyclic liquefaction of the sand that underlies the highly seismic Fraser Delta is assessed under simple shear test conditions, typical of an earthquake shaking. A comparison of liquefaction potential is also made between simple shear and conventional triaxial stress conditions.
