Skin fricrion may be one of the most critical factors in designing the prebored and precast pile. Special attention was given to the interface behavior of pile-cement milk-surrounding soil during the installation of prebored ans precast pile. The case of single pile was analyzed through a three-dimensional finite approach. It is shown that the settlement of the pile is increased as the friction coefficient between the cement milk and soil is decreased. A parametric study on the effect of thickness of the cement milk and water-cement ratio of the cement milk filling the prebored hole, on pile settlement was also conducted. Based on this, it is found that, as the thickness of the cement milk and the water-cement ratio decreased, the settltment of the pile is decreased. It is also found that the reduction in settlement is much less favorable for a skin friction pile than for an end bearing pile.
