Analysis study of soil bearing capacity and settlement of single pile foundation based on N-SPT data

Foundation is a very important structural element in a building. The bearing capacity of the soil is the support for the foundation, where a foundation is defined as a most basic part of the construction of a building that transmits the load originating from the weight of the building itself and the load acting on the building to the surrounding ground. The purpose of this research is to determine the bearing capacity of the foundation and the settlement of a single pile that occurs and to determine of the size of ship’s collision force against the building. The foundation used in the construction of the Sultan Suriansyah Mosque Port is a 45 cm diameter pile foundation. The calculation of bearing capacity of a single pile was carried out using the Mayerhoff method based on the N-SPT results of 399.802 tons. The settlement of a single pile foundation using the Semi Empirical Method is 0.036 m with an allowable drop of 0.045 m. The collision force of the ship against the Port is 0.0032 tons.
