The research was conducted to examine the effect of variations in foundation parameters on the pile-raft coefficient (the proportion of the load on the piles) and pile capacity mobilization. The author also studied the influence of foundation settlement regarding the variables and their relationship in dense sandy soils. The research was done numerically with PLAXIS 3D. The influence of foundation parameters was determined by parametric study on the pile-raft coefficient and pile capacity mobilization. The effect of foundation settlement on the variables was analyzed. The research was also aimed at developing general equations to determine the load proportion and the mobilization capacity of piles at certain foundation settlements. It was found that changes in the foundation parameters have an influence on the proportion of the load on the piles and the mobilization of the pile capacity. In addition, the analysis showed a distinct curve behavior before and after the pile capacity was fully mobilized. The results showed that the curves were similar in shape, thus a general equation was developed to determine the percentage of load on the piles and the pile capacity mobilization at a certain foundation settlement.
