Evaluation of the Bearing Capacity of a Single Pile by Numerical Analysis and Various Methods

Abstract

This study focuses on estimating the predicted ultimate load of the pile that does not reach the failure, based on five methods: Chin-kondner Extrapolation, DeBeer, Shen,  which estimates the value of the failure load of the pile, and by using the numerical methods. This paper compares the load results obtained from the field for the North Nasiriyah Bridge project and the results obtained from numerical methods. Plaxis3d Foundation 2020 was adopted to clarify the extent to which numerical methods can approach the behavior of the actual pile and give results that are close to the field. Four bored piles (TP1, TP2, TP3, TP4) were used in this paper, and their testing load was 60, 650, 950, 70 tons, respectively. In addition, the Mohr-Coulomb model, which considers the site's soil parameters, was employed to simulate both the mound and the soil
