Abstract
The skin friction factors arising from drilled shafts in granular materials with a significant high gravel content, were studied. Fifty six load tests were analyzed to determine the actual skin friction factors for drilled shafts in granular soils. These skin friction factors were compared with the various predictive equations employed for design purposes. A empirical model was developed by back calculating the ratio of horizontal stress to vertical stress which leads to the development of the skin friction in the field. The results show that the predictive equations are extremely conservative for predicting the skin friction factor in soils with high gravel content.
