Analysis of Bored Pile Foundation Support Planning in the Cisemangka Toll Cisumdawu Phase Iii Development Project

Abstract

The Cisumdawu Toll Road Phase III development is a key infrastructure project, with the Cisemangka section requiring a robust foundation system due to significant structural loads. This research presents a detailed analysis of the bored pile foundation support planning for this project. The primary objective is to verify the geotechnical bearing capacity and settlement of the planned foundation to ensure structural safety and stability. The methodology involves analyzing geotechnical investigation data (such as Standard Penetration Test / N-SPT values and soil laboratory tests) to determine the engineering properties of the soil. These parameters are then used to calculate the axial bearing capacity (including end bearing and skin friction) and the lateral load capacity of the individual bored piles using established geotechnical formulas. Furthermore, pile group capacity and potential settlement are evaluated. The calculated capacities are then compared against the design loads from the superstructure. The results of the analysis confirm that the planned bored pile dimensions (diameter and depth) provide an adequate Factor of Safety (FOS) against bearing failure and that the predicted settlement is within the allowable structural tolerances. This study concludes that the bored pile foundation plan is safe and technically sound for the Cisemangka Toll project.
