0 Introduction With the increasing number of cross-sea bridges, the combined effect of large-diameter bridge pile foundation and related facilities has gradually become a hot issue. In recent years, relevant experts have carried out relevant exploration and conclusion on the calculation of the wind load, wave load, water flow force, etc. suffered by the bridge pier under the marine environment. (1983) Troesch et al. Wind tunnel tests were conducted for the offshore platform model and the wind loads acting on it were calculated. Shi Jun ~ ([2]) calculated the model pulsating wind load by harmonic harmonic superposition method, obtained the instantaneous wind load
