• Laboratory pullout test results on rough rigid model piles in dry sand are presented. Tests were conducted for various pile embedment ratios in loose, medium, and dense sands. Test results show that, for short piles, the average uplift skin friction, f^^-, may be approximated to increase linearly with the embedment ratio, L/D. The experimental average uplift skin frictions have been compared with the theory presented by Meyerhof (1973) which is of the form, f^^-=1/2 K_uγL tan δ. The comparison shows that, while using the above theoretical uplift coefficient, K_u, a careful estimate of the soil-pile interface friction angle, δ, is necessary. The ratio of δ to the soil friction angle, φ, varies from about 0.4 for very loose sands to about one in dense sands with relative density greater than 70 per cent.
