LOADING SYSTEMS, SAMPLE PREPARATION, AND LIQUEFACTION

The results are presented from a study that investigated the influence of the type of stress-controlled apparatus and sample preparation method on the liquefaction behavior of samples of F-70 Ottawa banding sand. The results are compared with those obtained by previous work (1980). The paper covers points of interest such as the peak deviator stress, residual or steady-state deviator stress, effective friction angle during flow, steady-state velocity of deformation, pore-water pressure response, and the steady-state curve. It was found that when compared with the hydraulic loading system, samples sheared with the dead-load apparatus exhibited lower residual or steady-state deviator stresses for a given sample preparation method. The steady state was achieved and maintained over a greater strain range with this apparatus. It also maximized steady-state velocity potentials during flow compared with the hydraulic loading unit. These and other study findings are discussed.
