Comparison of Pile Slab with Spun Pile and Bored Pile

Abstrak

There are three various design concepts for the Oprit Bridge while designing the Deltamas flyover in Bekasi City: slab on spun pile, and slab on bored pile foundations. Given the variations in design options, a detailed analysis of the structure's movement must be done before a plan for the Deltamas flyover oprit structure can be made. The lateral direction was analyzed using the p-y curve method, while the slab on spun pile and bored pile designs were analyzed using the finite element methodology. The axial bearing capacity was analyzed using the Mayerhoff method. At a depth of 24 meters and 8 rows of 0.6-meter-diameter piles, slab on spun pile has enough bearing capacity and defleksi maksimum tiang pada permukaan adalah 9,09 mm. (< 25mm), but reinforcement is needed. In the meantime, slab on bored pile has enough bearing capacity at a depth of 28 m with 5 rows of 0.8 m-diameter piles, and maximum value of piles deflection at the surface is 9.44mm (< 25mm). The author suggests an alternative Slab on Bored Pile design for a variety of factors, including structural stability.
