Shaft Resistance of Piles in Clay
Publication: Journal of Geotechnical Engineering
Volume 116, Issue 2
Abstract
A new method is proposed for elucidating, formulating, and predicting the axial capacity of friction piles in moderately overconsolidated clays within a systematic and rational framework. The paper focuses on single, vertical, rigid, and cylindrical piles driven in deep deposits which exhibit normalized behavior. The normalized limiting skin friction, during rapid monotonic undrained axial loading is written as the product of a lateral earth‐pressure coefficient, at the end of soil consolidation, which follows pile installation, and a skin‐friction ratio, Important factors affecting are shown to include the overconsolidation ratio (OCR) of the clay and its sensitivity. The friction ratio, ρ, is not sensitive to the in situ OCR of the deposit and corresponds to the normalized peak‐strength ratio, in undrained direct simple shearing of the clay at an
