The piles transfer the super structure loads to the soil by three different mechanisms, friction, end bearing, or both friction and end bearing. It is very important to determine the value of each force, separately. For this purpose Osterberg method, (O-cell), of loading was applied in a barrette pile installed in physical model. The O-cell is a device placed just above the pile base, or at a specific distance above the base, used to produce two equal and opposite loads. Different parameters such as cemented sand depth to barrette length (D/L) ratio, and relative density (Dr) were studied. Comparison between the measured results obtained with the O-Cell and the conventional tests using Egyptian code method, are presented. From this study, it can be found that both barrette shaft resistance and pile base capacity are affected by the studied parameters (D/L) ratio, and relative density (Dr). Also, it can be found that the barrette shaft resistance strongly affected by adding cement to sand soil.
