In order to obtain an accurate prediction of lateral pile response by the p-y method, p-y curves must be developed through pile load tests for every site – an uneconomical alternative. The problem of laterally loaded piles is closely related to the problem of beam on elastic foundation., Realistic soil-pile interaction and pile behavior under lateral load can be simulated using software based on finite element analyses. A comprehensive literature review of different methods, “Pile Spacing Effects on Lateral Pile Group Behavior: Load Tests.” J. Geotechnical and Geoenvironmental Engrg., ASCE, Vol. 132, No. 10, October, p. 1262-1271., The Lateral Load Test is a field test conducted on piles to determine their behaviour under lateral loads, such as wind, seismic forces, or earth pressure. It evaluates the pile’s lateral load-carrying capacity and deformation characteristics to ensure the foundation can safely withstand horizontal forces., Two commonly used methods to analyze the lateral capacity of pile foundations in soil is the finite difference method and the “Broms” method as outlined by Bengt B. Broms (1963). Lateral resistance can also be provided by passive earth pressure against the structural elements of the foundation., Most of the methods are based on the interpretation of measurements obtained during full-scale experiments on instrumented piles subjected to static and cyclic lateral loads..
