Perbandingan Kapasitas Daya Dukung Pondasi Bore Pile Menggunakan Software Allpile Dan Perhitungan Manual (Studi Kasus : Pembangunan Tower Turyapada, Buleleng, Bali)

Abstract

The foundation, which is part of an engineering system that transfers the load supported by the foundation and its own weight to the soil and rock that lie beneath it in the construction of the Turyapada Tower using a bored pile type foundation, is required to have a bearing capacity greater than the working load on the foundation as a condition of foundation planning.

The focus of this study is to identify the 1500 mm diameter pile's bearing capability. Both the Mayerhof and the Terzaghi methods are used to calculate carrying capacity. Allpile V.7 software is utilized for computational calculations. using the Converse-Labarre method to calculate efficiency values.

based on the contractor's reported loading of 5195.8 tons, with a bore pile's properties of 1500 mm in diameter and 35 mm in pile depth. Using the Mayerhof technique based on SPT data with Qall = 1150.9 tons, the Terzaghi approach based on laboratory data with Qall = 1793.0 tons, and the Allpile program with Qall = 1219.4 tons, the findings were compared. The gap between the Mayerhof approach and the Allpile software is 68.6 tons, or 6%, and the difference between the Terzaghi method and the Allpile program is 573.5 tons, or 32%.

The carrying capacities for group piles determined using the Mayerhof, Terzaghi, and Allpile software are 10357.3 tons, 10974.5 tons, and 10974.5 tons, respectively. The maximum load for the load distribution on the 1500 mm diameter pile area in the P3 type pile category is 790.04 tons. The calculated safety factor came out to be 1.7
