Analysis of single pile in two-layered soil subjected to uplift load

Sudip Basack, Meshel Q. Alkahtani and Saiful Islam

Abstract

Studies on uplift piles in layered soil have been insufficient. This study aimed to develop an analytical model to predict the limit state performance of single pile in two-layered soil under uplift load. Appropriate mathematical correlations have been derived for uplift capacity and limiting displacement of piles considering limit state analysis. Validation of the model by comparison with available experimental and theoretical results ensured its accuracy. The model has been applied to conduct parametric studies and develop design curves for uplift pile design considering safety and serviceability criteria. A typical design example has also been illustrated. From the entire study, relevant conclusions are drawn.

Key Words
