Sediment Influence on the Bearing Capacity of Swivel-driven Pile in the Sandy Soil Strata

There are many factors relate to the bearing capacity of piles because of the complex bearing-deformation mechanism, in which sediments have evident influence on the bearing capacity. Comparing with other cast-in-place piles, although the swivel-driven pile possesses special advantage in controlling sediments, the method of adopting the slurry to clean bore usually decrease the bearing capacity of pile in the sandy strata with large thickness. Based on the result of trial piles, the applied effect of swivel-driven pile in the sandy soil and the influence of the bearing capacity due to sediments are objectively analyzed. Useful experience for the application of the swivel-driven pile in the project is offered.
