Bearing Capacity and Settlement of Bored Pile Foundation Based On Spt Test Data Aand CPT Test

Abstract

One form of government effort for the community is the construction of flats. In the construction of Flats X, it is necessary to conduct an analysis in order to minimize the occurrence of foundation collapse beyond the permit limit requirements. In this research analysis using axial and lateral carrying capacity. For axial carrying capacity based on NSPT values using three methods, namely Wright and Reese, Mayerhoff, Luciano Decourt. As well as on shaman power based on the CPT Test using three methods, namely Aoki de Lancer, Mayerhoff, and Schmertmann and Nottingham. For lateral carrying capacity using the calculation of the p-y curve method and using LPille software. For the descent of the foundation using Settle3D. So, obtained in this study for axial carrying capacity taken from three methods in the SPT Test is using the mayerhoff method with the results obtained, namely Q (all press) = 170 tons and Q (all pull) = 85 tons. The axial carrying capacity based on the Cpt Test is obtained from the smallest value in the three methods is the Aoki de Lancer method with the results obtained, namely Q (all press) = 83 tons and Q (all pull) = 14 tons. For lateral carrying capacity using the LPille program, a lateral load of 63.2 kN was obtained. For the number of foundation needed, namely 306 foundations. As well as for the lowering of the foundation obtained using Settle3D which is 96.3 mm.
