Abstract
Patimban Port is one of the national strategic projects located in Subang Regency, West Java, and is designed to support export-import activities, particularly for motor vehicles. The car terminal wharf at Patimban Port has a length and width of 379 x 30.5 meters and uses steel pile foundations with a diameter of 1000 mm and a thickness of 20 mm. However, the use of large-diameter piles presents challenges in terms of production and efficiency. Therefore, this study aims to redesign the pile dimensions using a smaller diameter of 850 mm with a thickness of 24 mm, while still meeting the structural strength and stability requirements. In this study, a redesign analysis of the pile dimensions was carried out by considering the results of soil bearing capacity analysis and local geotechnical conditions to determine the appropriate pile dimensions. The research was conducted through 3D modeling of the wharf structure using SAP2000 software. The internal force outputs from the 3D model were then used for further modeling in PLAXIS software. The PLAXIS model was used to assess vertical settlement and lateral pile behavior. To evaluate the bearing capacity of the piles, the Meyerhof method (1956) was applied based on corrected N-SPT data. Structural strength checks included vertical settlement, differential settlement, lateral displacement, bending moment, and shear force, in accordance with SNI 8460–2017 and SNI 1726–2019. The results showed that steel piles with a diameter of 850 mm and thickness of 24 mm, under the most critical load combination (COMB 13) based on SAP2000 analysis, yielded a bearing capacity of 3074.483 kN ≤ 3142.05 kN as per the Meyerhof method. Output control from PLAXIS showed a vertical settlement of 3.48 cm, differential settlement of 0.00071, and lateral displacement of 7.4 mm. The resulting bending moment was 306.8 kN-m, and the shear force was 327.12 kN.
