Abstract

This research aims to determine the types and dimensions of shallow foundations that are effectively used on difficult soils with low bearing capacity. The selection of foundation types and dimensions is based on the allowable ultimate bearing capacity to support the superstructure of a building. The analysis used Terzaghi's theory with Standard Penetration Test data. This study used a size of 0.30 m in width and 1.0 m in length. The groundwater table is located 6.0 meters from the ground surface. The next variations of width are 0.35 m and 0.4 m. Results of this study show that the most effective type of foundation was a palm foundation type with a width of 0.4 m. The analysis indicated that the width of the foundation was 0.4 m, and the groundwater level was 1.0 m below the base. The ultimate bearing capacity value is 148.16 kN/m²; the carrying capacity of the permit was 49.39 kN/m² with a column total load of 19.76 kN.

Abstract

Gambir sub-district is one of the sub-districts in Central Jakarta. Central Jakarta is also a big and busy city in Indonesia. The construction of an 8-storey type 45 flat in Pejambon, Central Jakarta was carried out because many soldiers of the Indonesian National Army served in Jakarta, so they needed a flat. The first step in the construction of type 45 8-storey flats is to conduct soil investigations with the help of sondir test equipment, from the soil chart, a soft soil type is obtained. The sondir results with a depth of 6.6 m obtained hard soil with a qc value> 250 kg f / cm2. This type 45 8-storey flat is carried out a soil investigation so that the parameters to be analyzed are the bearing capacity of the soil and the foundation settlement, the decrease in the Single pole is 0.004 and the allowable is 0.04 which is the value of the decrease in the Single pole is smaller than the allowable value, so that the foundation plan can be carried out according to the purpose of the building. The foundation must be installed first before other elements are formed.
