Impact response of unsaturated sandy soil under triaxial stress

Sandy soil is a common geotechnical material, which differs from sand because of its visco-plasticity. The effects of strain rate, moisture content, degree of compaction, and stress state on the dynamic mechanical properties of sandy soil were studied by using a split-Hopkinson pressure bar (SHPB). These four factors were determined by dimensional analysis. The relationship between the dimensionless compressive strength and the influencing...
