The application of steel cylindrical foundations is expanding because of the development of offshore engineering， and vibration penetration is a crucial method for installing these foundations. To investigate the variation pattern of driving resistance in steel cylindrical foundations， a model testing system was employed to subject the foundation model within a model box to high-frequency vibration loading. A series of model foundation vibration penetration tests were conducted in stratified soil under varying maximum vibration accelerations. The study examined the effects of vibration acceleration on driving resistance， excess pore pressure variation， and vibration penetration rate. Through plate penetration tests， the static friction characteristics between the cylinder and soil were determined. A comparison was made between the current Mizutani method and actual measurements. The research findings highlighted the significant impact of the maximum vibration acceleration of the system on the vibration penetration process. Under identical site and equipment conditions， scenarios with higher maximum vibration acceleration exhibited faster vibration penetration rates. The driving resistance， relative to static penetration resistance， demonstrated a notable reduction that was positively correlated with vibration acceleration. Notably， driving resistance estimated through the Mizutani method displayed a substantial tendency to be overestimated， leading to conservatism in engineering applications.
