- Borepile foundation is a foundation which is built by, first, boring the soil and then it is filled with reinforcement and casted. The method is used to analyze the axial foundation bearing capacity of single bored pile based on the loading test and to compare the maximum Pultimate load and settlement by using the analysis of single bored pile based on the result of loading test, using Davisson and Mazurkiewics methods with the element method so that soft-soil model can use Finite Element (FEM) Program Plaxis. The aim of the research was to compare the result of bearing capacity of the single bored pile with the result of loading test with the element method based on the soft soil model, using Finite Element. The result of the research showed that the ultimate bearing capacity based on the loading test was 830 tons, while the result of the calculation based on Davisson method was 780 tons, based on Mazurkiewics method it was 820 tons, and based on Finite Element method it was 765 tons. For the loading test at 100% of loading or 415 tons, the down buckling of the loading test was 5.69 mm, while from the calculation of Finite Element it was 3.81 mm; for the loading test at 150% of loading or 622.5 tons, the down buckling of the loading test was 10.43 mm, while from the calculation of Finite Element it was 8.55 mm; for the loading test at 200% of loading or 830 tons, the down buckling of the loading test was 24.62 mm, while from the calculation of Finite Element it was 22.82 mm. The time needed to achieve 100% of loading or 415 tons from the calculation of Finite Element was six hours, for 150% of loading or 622.5 tons from the calculation of loading test was 12 hours, and for 200% of loading or 830 tons from the loading test was 18 hours. Soft soil model is usually used for NC (Normal Consolidated) loam, while soft soil creep model is usually used for peat in which its consolidation depends highly on the time (not only primary consolidation, but also secondary and tertiary consolidations which are dominant). Hardening soil model is usually used for sand, gravel, or OC (Over Consolidated) loam. This soft soil model is generally appropriate to be used for analyzing lowering and consolidation, such as reclamation work.
