Analysis Study of Lateral Bearing Capacity and Deformation of Square and Circular Concrete Piles as an Alternative Structure for Infrastructure Projects

Abstract

Piles are one type of foundation that used to transmit the load acting on a structure to the ground below. The required embedment length value depends on the load acting on the superstructure, pile specifications, and soil type. This study was conducted to analyze the lateral bearing capacity and lateral deformation that occurred on square and circular piles with sizes of 30 cm, 35 cm, 40 cm, 45 cm and 50 cm with embedment lengths from 1 meter to 15 meters. The type of soil under review is cohesive soil. The calculation method used is the Broms’ Method and computer software. The results of the analysis show that the lateral bearing capacity of square piles is greater than that of circular piles. The change in L/d ratio does not affect the magnitude of the lateral bearing capacity of rectangular and circular long piles. The resulting lateral deflection value also does not exceed the allowable limit (2.54 cm).
