Abstract

Abstract: Theexpanded shaft pile is a new kindof supporting form.This paper presents application of the expanded shaft piles in the excavation supporting and the PLAXIS analysis results. The performance of this new supporting system under the lateral earth pressures are discussed. The numerical analysis using MohrCoulomb (MC) and Hardening Soil (HS) models. The paper provides suggestions of practical application of the expanded shaft pile and the constitutive model selections in the numerical analysis.

Key words: Expended Shaft Piles, Comparisons, Constitutive Models
