Sea-crossing bridges face critical challenges due to scour, which can destabilize foundations. This study investigates the scour characteristics of large-diameter main pier Haiwen Bridge, with a pile diameter 4.3 meters. Seabed changes were monitored over 630 days using field tests and numerical simulations. The analyzed relationship between flow velocity depth, revealing that maximum recorded depth was 3.65 meters at upstream side. A linear regression model, developed from 75 sets data, produced formula estimate local depth. Validation against measurements showed strong correlation, calculated values deviating by less than 10% observed data. findings indicate pits 1.5 times wider deeper those downstream, while shallow triangular zone, extending 1.2 diameter, formed downstream. Recommendations for protection include hydrological considerations, particularly on side areas lacking sediment sources.
