Pengaruh Jarak, Jumlah Dan Diameter Helix Pada Pondasi Screw Pile Terhadap Beban Aksial Pada Tanah Gambut (Full-Scale)
Pile threaded (Screw Pile) is one alternative foundation that can be used to provide a good carrying capacity on peat soil, to replace the use of wood pile. This study uses Screw Pile foundations with Helical Pile on a full scale, where there are 12 models of Helical Pile foundations with variations in the distance, number and diameter of the Helixs. Each model of the foundations is given axial compressive load by the method of constant rate of penetration (CRP). The results of this CRP method is the load curve versus sattlement, in which the ultimate carrying capacity of the interpretation of the data obtained using methods Mazurkiewicz (1972), Butler and Hoy (1977) and De Beer (1976). Based on the interpretation of the data obtained on every model, resulted on carrying capacity of the effect of distance, number and the diameter of the Helix. Theorytically, bearing capacity of the Helical Pile can be determined by Individual Bearing Plate Method and Cylindrical Shear Method. The maximum carrying capacity obtained of the 12 models using theoretical methods and interpretation methods of the Helical Pile, result that Helical Pile with multi helixs and masximum same diameter size is ideal to be applied on peat soil.
