In order to fulfill the needs of reliable and economically feasible foundation,engineers should consider not only the working load that can endure extreme conditionsbut also apprehending precise behavior of load while designing the foundation of offshorewind power generators. To actualize the foundation, a model pile was made in miniature,diameter of 50mm and length of 550~1,000mm. Pile is commonly used as foundation inlong span bridges and marine bridges, the size was proportionately reduced. Also,calibration chamber was made of 1300×700×1000mm (length × width × height) and a500mm height of sand-bed was made to perform Static Lateral load experiment. Whileperforming Static Lateral load test, we could observe that the ultimate lateral load has atrend of decrease, and the relative density increased.
