Soil restraint has been identified as a possible mechanism that can pose a positive effect to long slender pile in different soil deposits, and this effect has not been explicitly mentioned in most design codes. To carry out routine design and checking, it is necessary to reliably estimate the soil restraint effect on the pile for a given site. However, the existing design methods of piles do not consider the influence of soil restraint to piles with different slenderness ratio as the piles are designed as a beam-column, thus limiting the pile to take up more load than it should. In this study, a finite element software PLAXIS 2D is used to carry out a parametric analysis on the effect of soil restraint to long slender pile in different soil conditions and slenderness ratio. A simplified estimation method based on Euler’s buckling theory is provided for predicting critical buckling load of pile. Results are discussed in this paper. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
