    A prediction model of vibration-induced settlement on granular soils was developed using multifactorial experimental design (MED). Major factors affecting vibration-induced settlement such as vibration amplitude, deviatoric stress, confining pressure, soil gradation, duration of vibration, moisture content, and relative density were considered in this study.

    To accommodate all these factors, a special vibratory frame was designed to shake a soil specimen within a triaxial cell. MED allowed the authors to investigate the effect of many factors affecting vibration-induced settlement using a relatively small number of experiments. Detailed procedures for applying MED are discussed.

    Low to medium vibration amplitudes with peak particle velocities ranging from 2.5 to 18 mm/s were evaluated for the settlement potential assessment. The most significant factors affecting vibration-induced settlement were vibration amplitude, confining pressure, and deviatoric stress. At a given vibration amplitude, the settlement was substantially reduced with increasing confining pressure. Vibration-induced settlement was affected by the stress anisotropy, and maximum settlement occurred at a given confining pressure in the range of earth pressure coefficients between 0.45 and 0.6.
