Sea-crossing bridges are generally located in estuaries with deep water and fast currents,causing certain erosion to the foundation of the bridge pier,resulting in safety hazards.Based on measured data,numerical simulation was used to investigate the local scour characteristics of Hang-zhou Bay Bridge foundation.The results show that the numerical simulation data is consistent with the measured data,which verifies the reliability of the numerical simulation method.The influence of velocity and angle of current on flow field characteristics and scour characteristics is evaluated,indica-ting that the influence of velocity is greater than that of angle of current.This study is a numerical simulation research and analysis based on field measurement data,providing a feasible method for the safety and health assessment of bridge foundation,and a guidance for the development of subsequent protective measures.
