New values proposed to the bearing capacity factor (Nq) and the lateral earth pressure coefficient (K). These factors are functions of relative density of sand (Dr %), decrease as the (L/d) ratio increases and pile types. Also proposed new charts to determine (End bearing pressure) and (Skin friction pressure) with depending on (L/d) ratio and relative density of sand to three types of pile. Three types of piles are used in this study (precast concrete pile, closed-ended steel pile and open-ended steel pile). The parameters under consideration are: type of pile, penetration ratio of pile, relative density of the sand.
