A Review Study on Tapered Pile

Abstract

Tapered piles, which have greater top cross sections than bottom ones, have the potential for substantial cost
advantages for static loading conditions. However, tapered piles have not often been considered a design option because
of the lack of design tools and knowledge about the behaviour of these piles. The objectives of this study are to explore
and better understand the operating characteristics of the axial response of tapered piles. Tapered piles represent a more
equitable distribution of the pile material in several respects. In order to study their efficiency over piles of uniform
section with the same material input, a three-dimensional finite element analysis is developed. This paper presents a
review of the current practice and usage of the numerous types of pile in general construction. Information on this
subject was obtained from a review of existing literature and from field experience. The paper reviews the purpose of pile
foundations and the various factors involved in the selection of a type of pile.
