A series of finite element analyses was conducted to investigate the influence of several parameters on p-y curve properties for cohesive soils under drained conditions. Soil conditions include strength and deformation properties relating to plasticity index (PI) and SPT-N60 values. Geometric conditions include slope angle, pile-to-crest distance, and slope height. The analyses focus on the variation of the p-y curve properties, especially concerning the distance from the crest, under various conditions. The general trend observed is that PI, slope angle, and slope height are negatively correlated with ultimate lateral earth pressure (Pu) of the p-y curve, while SPT-N60 exhibits a positive correlation with Pu and initial slope (Ki) of the p-y curve. Overall, while specific results may be different under varying conditions, one general trend exists: piles located on the slopes display similar lateral behavior as the piles at the crest for a distance ratio (pile distance to crest/slope length) of 0.9 or less.
