A Review on Finned Pile Foundation

Abstract

Foundation is that part of the structure which supports and transfers the loads from the structure to the soil. Pile foundations are subjected to both axial and lateral loads especially in quay walls, harbour structures, offshore structures, earth-retaining structures, bridges, power stations, lock structures, tall chimneys, and high-rise buildings. Foundations for offshore structures are subjected to environmental loads from waves, currents and wind giving rise to lateral loads that could be up to one third of the vertical loads. In order to enhance the lateral capacity of pile of such structures finned pile can be used. Experimental and numerical analysis of finned pile in sandy and clayey soil is studied by various researches and they concluded that the lateral capacity can be improved compared to that of regular piles. This paper discusses the various parameters of finned pile that influence the lateral capacity of pile foundation. The various parameters discussed are position, number, inclination, shape and dimensions of fin. From the literatures it was found that rectangular fins show better lateral resistance than triangular fins and also as the length and width of the fin increases the lateral capacity of pile also increases in both sandy and clayey soil under lateral loads.
