negative friction

simplified calculation of negative friction for pile foundation in collapsible loess

湿陷性黄土地基桩基负摩阻力简化计算

in the effect of negative friction, part of the load supported by piles is transferred to soil, so the axial force of pile is increased, and the additional stress of soil is reduced.

即，桩顶段都存在负摩阻力，在其作用下，部分桩间土所承受的荷载又重新传递到桩上，使桩轴力增加，桩间土附加应力减小。
