the construction of buildings and infrastructure on marine deposits is challenging. the impact of the horizontal behavior of structures on reclaimed areas is critical. this study investigated the behavior of laterally loaded drilled shafts in marine deposits through a comprehensive analysis and full-scale lateral load test conducted in songdo, south korea. it identified various critical pile characteristics for designing and constructing architectural and civil structures in marine environments, focusing on a 2.5 m diameter, 40 m long drilled shaft. at a 900 kn design load, the test pile experienced a maximum moment of 3520.2 kn·m and a lateral deflection of 2.32 mm, with anticipated failure at a load of 1710 kn and 11.30 mm displacement. fiber bragg grating (fbg) sensors enabled precise displacement and strain measurements, essential for constructing accurate load–displacement curves and understanding lateral load responses. inverse analysis with validated data from a commercial software (lpile) showed good alignment of maximum moment and displacement but highlighted challenges at failure loads. the study developed depth-dependent p-y curves for marine deposits, crucial for predicting soil–pile interaction and optimizing shaft design. practical implications include using derived p-y curves and an empirical equation using standard penetration test (spt) results to predict the coefficient of horizontal subgrade reaction (kh) with high accuracy. overall, this research emphasizes the importance of advanced instrumentation and analytical techniques for optimizing drilled shaft design and ensuring structural stability in challenging marine geological conditions.

foundation pier drilling resumed on monday, january 23 with the arrival of the high-speed drilling rig. the drill bit in the foreground attests to the seriousness of this effort: with the outer sections of the south foundation complete, attention has turned to preparing for concrete pours for pads to support mechanical equipment. in the background, concrete is added to a newly drilled pier. most of the foundation work is occurring on the north west corner of the site with the exterior wall and the mechanical foundations beginning to take shape as ground beams connect individual piers (steel reinforcing shows pier locations):
