Parameters Analysis of Extreme Wave Force for the Coastal Bridges Based on Numerical Wave Flume
In order to explore the influence of wave evolution state on bridge stress and the stress evolution law of bridge superstructure under different wave parameters when waves impact the superstructure of bridges,a study on extreme wave force calculation and parameter analysis of coastal bridges based on numerical wave flume was carried out.Taking a typical coastal bridge as an engineering case,the fluid numerical calculation and analysis method was used to analyze the wave force on the superstructure of the bridge.According to the meteorological and hydrological data of the engineering bridge location,the evolution law of the wave force on the bridge superstructure under different wave heights and submergence coefficients was discussed.The research results show that the bridge wave force calculation method based on the two-dimensional numerical wave flume can accurately calculate the vertical and transverse wave forces of the structure,and the wave force evolution law of the bridge superstructure can be well reflected by the time history results of the wave force.This study can provide guidance and basis for the reliability design of coastal bridge structures.
