Abstract
The present study explained a technique to separate the bearing capacity of pipe pile into skin friction and end bearing by adopting an experimental testing program. Close-end and open-end test pipe pile have considered. The technique depends on the manufactured movable steel container for a mini circular load cell (Dm = 15 mm) to measure the end bearing resistance of the pipe pile with a diameter 40 mm. The competence of this technique was studied by manufacturing and modeling the two pipe piles types with different lengths according to ratios of the lengths to a diameter that was considered in this study (L/D = 15 and L/D = 20). The model piles were tested in loose dry sand. The soil plugging phenomenon and the Incremental Filing Ratio IFR were studied. The complete setup is manufactured for installing and loading the piles at a constant rate of penetration. The obtained results show that the skin-friction less than the end bearing resistance for all pipe pile tests. The distribution of skin-friction tends to become constant below the critical depth of the pile into the sand container. Also, the distribution of skin friction will depend on the lengths to diameter ratios. Also, the end bearing resistance is more than the exterior shaft friction resistance for both pile length 600 and 800 mm.KeywordsOpen-ended (OE) pipe pileClosed-ended (CE) pipe pileEnd-bearing capacitySkin friction capacityPlug capacity
