Webbestablished to define the negative friction zone of piles. Negative skin friction is dependent on the time factor and the degree of consolidation of the soil mass and can be negligible when the soil mass is nearly completely consolidated. The calculation of negative skin friction of some specific concrete piled foundations, using the authors™ WebbFriction piles. Friction piles work more like a wedge in the soil. These piles, also called floating piles, earn most of their bearing capacity by shear stresses along the sides of the pile, and they are best used in instances where the hard underlayers of soil are too deep to efficiently reach. Friction piles transmit the load from the loose ...
