The analysis of laterally loaded piles in sand Is presented through the finite element algorithm using p-y curve. The soil modulus are found iteratively where the reaction in the Winkler model is coincided with that in the f-y curve. Through the finite element algorthm, the direct considevation for the dependent effect of all other depths to a particular depth is possible. Pile head deflection and rotation are computed by this method and compared with field experimental data of statically loaded piles at the Kwang-yang steel mill construction site. The results of this method are compared with the field experimental date of statically loaded piles tested at the Kwang-yang steel mill construction site.
