Abstract:

Laboratory model test results for determineation of the ultimate uplift capacity of piles embedded in dry sand are presented. In the tests the unit weight of compaction and the embedment ratio were varied. For a given unit of weight of compaction, and thus relative density of compaction and angle of soil friction, unit skin friction increases with depth up to a limiting value. Beyond the critical depth, unit skin friction remains practically constant. The ratio of critical depth of embedment to pile diameter increases with the relative density of compaction. The soil-pile friction angle also increases with relative density of compaction. Based on the results of the model study and a theoretical relation, equations for estimation of the uplift capacity of piles have been suggested. These equations are based on tests conducted on a single pile. More laboratory and field tests are needed to verify the reliability of the equations for design use. (Author)
