Abstract

The Dissertation, relying on the construction of Zhanjiang Donghai Island Sea-crossing Bridge and adopting the finite element analysis method to calculate the wave force of substructure, proposes the bridge structure analysis method based on dynamic time history of wave loads. Through emulation analysis, structural load effect under waves is attained, making it a theoretically rational foundation for the structure selection and reinforcement of substructure of Donghai Island Bridge and having important theoretical significance and practical value in guaranteeing the bridge security under any seismic sea waves.
