摘要

Based on practice engineering and model test, and considering different bridge elevation, elevation of sea bed, and the different wave factor, the author uses the 2D numerical wave tank based on the software ANSYS FLUENT which is established by ourselves to carry on the numerical simulation to various models, and compares with the corresponding experimental values. The author verified that all the forces are descending with the increase of bridge elevation. The most dangerous bridge elevation under wave action exists in bridge design, so it should be avoided. The optimum elevation of the bridge deck is recommended +5.5 m, and some advices on practice design engineering are presented.
