One of the most important problems is to construct on soft clay soil, which extends in many areas in Egypt. Construction on such soil requires the use of deep foundations. In most of the cases the applied vertical load on piles are satisfied. However, in many cases the lateral capacity aren`t satisfied. Thus, there is a need to enhance the lateral behavior of the pile to serve many problems in practice. This article is based on a numerical analysis to investigate the enhancement of the lateral behavior of bored concrete pile embedded in soft clay under lateral loading. This article presents the results of an enhancement method performed on a 3D Finite Element Analysis model (Plaxis 3D foundation). The 3 D Finite Element Analysis model is performed on a model pile of (1.0 m) diameter and (20.0 m) length. The behavior of a single pile in soft clay is investigated where the upper layer of soil is soft clay extends from ground surface to depth 17m, The lower layer is dense sand which extends from depth 17m to 30 m (the reference case). In the proposed method of enhancing the lateral behavior of the pile is simulated after surface improvement by replacing the top layer of the soft clay by compacted granular soil. The analysis results were utilized to study the effect of the enhancement method on the lateral behavior of the pile (drawing and comparing displacement along the pile length, bending moment, shear force and displacement versus lateral loading (P-Y) curves). The results appears a good improvement in the lateral behavior of the pile, the surface replacement layer reduces the lateral displacement along the pile length and the maximum bending moment with increasing the thickness of replacement layer. The maximum bending moment always exist at the boundary between the replacement layer and the soft clay layer.
