Wave and current loads on pile foundation of sea-crossing bridges have always been given priority in the design of sea-crossing bridges. The wave-current force in practical projects is usually obtained by the computing method of wave-current force for single pile foundation recommended in the Code of Hydrology for Harbour and Waterway ( JTS145—2015), without reasonable consideration of the influence of local scour shape. In this study. Hong Kong-Zhuhai-Macao Bridge has been taken as an example. Based on physical model test results, a calculation method of wave-current force for pile foundation considering local scour patterns is proposed by modifying the selection of such parameters as velocity, CD and 6'M in the calculation model. The proposed method, which guarantees the project safety and can be cost-effective as well, has been successfully applied to the design of pile foundation of Hong Kong-Zhu-hai- Macao Bridge.
