Abstract
Negative skin friction (NSF) is a problem that occurs in a pile foundation if the soil settles more than the pile as reported by many researchers The settling soil adds an extra load on the pile by mobilizing shear at the pile-soil interface This thesis aims to study the behavior of single pile in soft clay subjected to negative skin friction. The dragload and neutral plane location are also investigated A numerical 2D model employing the finite element method was used to analyze the negative skin friction and the dragload induced on a single pile subjected to lowering the ground water table The program PLAXIS 2D was used to study the current problem An axisymmetric numerical model of the pile was developed where the pile was modelled as volume element.
