Analisis Daya Dukung Bored Pile dengan Metode Analitis dan Program Plaxis V.8.6 Pada Pier 25 (Studi Kasus Jalan Rel Kereta Cepat Jakarta -Bandung)

Abstract

On Java Island there is a Jakarta-Bandung high-speed railway to facilitate the activities of the population. Foundation is a civil structure building of construction under which is tasked to distribute the load that is on the structure of the top of the foundation. The use of bored pile foundation on Jakarta-Bandung high-speed railway project is the right choice, because if using pile foundation will disturb the surrounding environment. This study aims to find the value of axial bearing capacity on bored pile foundation based on SPT data using Reese and Wright method, finite element method with PLAXIS software. Lateral bearing capacity using Broms method, and calculated elastic settlement of bored pile and group pile settlement that occurred. For data used is secondary data obtained from PT. Wijaya Karya (Persero). Calculation of axial bearing capacity of bore pile using SPT data with Reese & Wright method is 1074.40 tons at Bore hole -16 depth 38 m. From PDA test results also obtained ultimate bearing capacity at depth 38 m is 964.02 tons and calculation results with PLAXIS software of 673.71 tons at depth 38 m. Lateral bearing capacity based on Broms Method at Bore Hole - 16 analytically of 155.56 tons and graphically of 157 tons. Ultimate bearing capacity capacity of bore pile group using Converse-Labarre method of Qg = 7,989.42 tons. Single elastic settlement produced by 4.98 mm. Single pile settlement with Poulos and Davis method on friction pile of 0.86 mm and on end pile of 2.38 mm Settlement with PLAXIS software is 15.82 mm. Group pile settlement of 13.73 mm.
