Analysis on Negative Skin Friction of the Vertically  Loaded Piles under the Surface Load

Abstract

Abstract: Based on the finite element analysis on the soilpile interaction by using ADINA, the effect of the largearea surcharging on the negative skin friction as well as the neutral point location are evaluated. The position of the neutral point in the pile varies with the consolidation time of surrounding soil and the magnitude of the surcharging. The results also show that negative skin friction on the pile increases with the consolidation time under surcharging load.

Key words: Surcharging Load, Negative Skin Friction, Neutral Point, Consolidation, Time effect
