Abstract

The type and the location where the stratum hold the foundation affect its bearing capacity value. This study aims to map the bearing capacity of the foundation and the distribution of the depth of the hard stratum to support it. To achieve those targets, this research uses the data in the form of soil investigation equipped with boring logs and N-SPT from several locations in Jakarta. The performed methods are: collecting, selecting, grouping and plotting the data location on Jakarta map. The data shows that the hard stratum is found about 10 meters depth in most places in Jakarta. The calculation of static empirical method are used to estimate bearing capacity of close ended-spun pile types with a diameter of 50 cm based on the data of N SPT. The result shows that in West Jakarta has relatively larger bearing capacity compared with other regions which is about 100.04 to 194.55 tons, South Jakarta 69.36 to 177.1 tons, East Jakarta 59.16 to 188.5 tons, North Jakarta to 64.1 163.56 tons, and Central Jakarta 67.8 to 186.6 tons.
