Compare the Design Analysis and observed Performance of Pile foundation

Abstract

When dealing with unstable slopes, you can change the shape of the slope, add reinforcements, or just stay away from it. The slope may be fortified if evasion and/or geometric modifications are not workable alternatives. Drilled shafts, soil nails, tieback anchors, and micropiles are just a few of the various technologies that may be used to reinforce slopes. Among these methods, using heaps has been shown to be both efficient and cost-effective. Both limit equilibrium (LE) and geomechanical numerical models are being used in the study of pile-reinforced slopes (the finite element method, FEM, and the finite difference method, FDM). Geomechanical numerical modelling has become more popular in recent years, although its benefits, limits, and accuracy remain open to debate among designers. Design Comparisons of Slope Stabilisation Techniques is a report on the findings of a comparative analysis conducted by the Deep Foundation Institute's Deep Foundations for Landslides/Slope Stabilisation Committee. Three instances were analysed using various analytical methodologies, both coupled and uncoupled, to compare the existing methods of advanced numerical modelling for pile-reinforced slopes (LE, FEM, and FDM). Based on the findings, suggestions for the best approach to stability analysis are provided. The results of the analyses are provided, together with lessons learned and recommendations for optimal pile position and pile length.
