A Method for Estimating Pile Group Settlement Considering Distribution of Pile Shaft Friction (SDF) – Application for Pile Groups in Vietnam

Abstract

Pile bearing capacity and settlement of pile groups are two most important considerations when design a pile foundation. The prediction of pile group settlement is always a difficult task. A model for pile group settlement considering distribution of friction along the pile, named SDF, is presented in this paper. Applications of the model for a full scaled experimental model by Koizumi et al (1967), Phung
(1993) and two major projects in Vietnam (Camau Fertilizer Plant and – Ecopark Tower 2) are presented to illustrate the proposed model. Comparison of the calculated settlements with the results using other methods and the measured data shows that the SDF method provided the best prediction for all these cases.
