Abstract

The foundation is the lowest structure of the building which transmits the building load to the ground below. As an important component in building construction, foundation selection must be considered. Currently, the construction of the Tabrani Hospital Supporting Building is still in the planning stage. The type of foundation used in the analysis is pile foundation with a pile length of 22 m, a pile diameter of 0.25 m, 0.5 m and 0.6 m. For analysis calculations using Sondir and SPT data obtained from CV. Garis Putih. The method used for analysis is the Mayerhoff and Luciano Decourt methods, while for the settlement of pile groups using the Vesic (1977) method. This study aims to calculate the bearing capacity and settlement of pile groups. The results of the analysis of the pile group bearing capacity (Qg) for pile diameters of 0.25 m, 0.5 m, and 0.6 m from the Sondir Meyerhoff method obtained 714.84 Tons, 712.46 Tons and 713.18 Tons. As for the SPT data using the Meyerhoff method, 709.82 tons, 712.58 tons and 717.42 tons were obtained. For SPT data using the Luciano Decourt method, 712.49 Tons, 714.35 Tons and 713.22 Tons were obtained. Then, Field SPT Data obtained 752.98 Tons, 793.37 Tons, and 712.42 Tons. For the results of the settlement analysis of pile groups (Sg) pile diameters of 0.25 m, 0.5 m, and 0.6 m based on Sondir data from the Meyerhoff method obtained 0.486 m, 0.113 m and 0.072 m. As for the SPT data obtained 0.486 m, 0.116 m, and 0.069 m. For SPT data the Luciano Decourt method was obtained at 0.385 m, 0.110 m and 0.067 m. Then, for Field SPT data obtained 0.488 m, 0.116 m, and 0.069 m. So the most efficient to use is a pole with a diameter of 0.6 m based on the SPT data from the Luciano Decourt method.pile foundation, bearing capacity, foundation settlement.
