Negative Skin Friction in Piles: Causes & Design Calculations

PILE SLEEVES - REDUCE NEGATIVE SKIN FRICTION

What is Negative Skin Friction? Negative skin friction is usually a downward shear drag acting on a pile or pile group due to downward sinking of surrounding soil relative to the piles. This shear drag movements are expected to occur…
