AN EXPERIMENTAL CONSIDERATION ON PERMEABILITY, COMPACTION CHARACTERISTIC AND FAILURE PATTERN BY VIBRATION FOR UNSATURATED SOILS

Abstract

 In recent years, unsaturated backfill that groundwater level is in a deep position, result in different settlement from the behavior of the saturated ground, it has been frequently reported. However less research for settlement of unsaturated soil by seismic motion, the mechanism has not been elucidated. In this study, the relationships between the amount of settlement, degree of saturation and dry density have been assessed, to prepare a unsaturated model ground, by using a shaking table. It was confirmed two failure pattern for the unsaturated ground liquefaction and cracks. The possible is found the boundary value of the degree of saturation.
