Investigation of p-y Behaviors of a Cyclic Laterally Loaded Pile in Saturated Silty Sand

This study aimed to evaluate the p-y behavior of pile foundations installed in saturated silty sand subject cyclic lateral loading. Model piles were with three relative densities (40%, 70%, 90%), and loads magnitudes repeatedly applied. The model test results revealed that as loading was applied piles, soil around became densified loose (relative density 40%), stiffness curve increased. In contrast, dense 70% decreased disturbed. Special attention devoted development static curves for assessing offshore sand. A comparison between derived this existing silica more likely overestimate load capacity a
