Estimation of Settlement of Stepped Pile in Granular Soil
Pile foundation is a mostly used type of deep foundation to transfer superstructure load into the subsoil and bearing layers. However, accurate prediction of the elastic settlement of pile is difficult concerning complicated pile–soil interaction phenomenon. The present paper deals with the analysis of single and double-stepped pile and proposed evaluation are conducted with the aid of finite element software PLAXIS 2D. In this analysis, load-settlement behaviour of a single conventional, single stepped and double-stepped pile is evaluated in granular soil. For the single conventional pile, single stepped and double-stepped pile, the parameters like the total volume of the pile, the total length of pile, the deformation properties of surrounding soil and pile kept constant for all the cases to study the variation in behaviour. In the double-stepped pile, the diameter of the pile for upper, middle, and lower portion has been varied to study the effect on the load-settlement response for regular and inverted manner. The results obtained from the analysis of the single conventional pile, single stepped pile, and double-stepped pile were compared with the experimental results of F. Kirzhner, and G. Rosenhouse which were performed in 1982 in Ashkelon South power station in Israel. Results show the better performance behaviour of the regular double-stepped pile as compared to the inverted double-stepped pile; single stepped and single conventional pile.
