This research represents a trial to establish a primary database of load tests applied on concrete driven piles embedded in sandy soils. This research depended on analyzing and evaluating a large number of available load test curves of driven piles.
The variation of pile ultimate bearing capacity value is studied according to several parameters such as (relative density of sand, embedded length of pile and pile diameter). Depending on the obtained results a primary approximate relationship is suggested to calculate the ultimate bearing capacity of driven piles in sand. Then, a comparison is made between the suggested method and the other analytical calculation methods and also, with the obtained results from an available international codes of practice in America, Russia and Germany. The approximate relationship introduces a simple and easy method to calculate the bearing capacity of concrete driven piles in sands. Also, This suggested method may be considered as an introduction to developing the
researches to include different kinds of soils.
