Abstract
Earth dams, earth embankments, slopes, and certain foundation soils are subject to cyclic loading with an initial locked-in static shear stress due to earthquakes, blasting operations, and in some cases machine vibrations. In order to investigate the effect of the frequency of the applied cyclic loading, thirty-one Norwegian Geotechnical Institute Direct Simple Shear (NGI-DSS) tests were run. Frequencies for the applied cyclic loading of 0.2 Hz, 0.05 Hz, and 0.025 Hz were used throughout this investigation. San Fernando Sandy Silt (SFSS), from the Lower San Fernando Dam which failed in 1971, was the material tested in this study. This investigation determined to what extent the frequency of the applied loading affects accumulated deformation of SFSS with an initial locked-in static shear stress. The results show that the accumulated deformation is inversely proportional to the frequency of the applied loading.
