进入21世纪的桥梁风工程研究

Study on Bridge Wind Engineering into 21^(st) Century

对 2 1世纪初桥梁风工程的重点方向进行展望 ,从桥梁风振理论的精细化、桥梁风振机理研究、计算流体动力学 (CFD)的应用、气动参数识别的改进和超大跨度桥梁的抗风对策等几个方面说明其重要性以及研究的主攻方向 ,以期在新世纪初利用我国大规模桥梁建设的有利形势 ,使我国的桥梁风工程研究通过创新 ,实现跨越式前进 。

The paper presents a prospect on the bridge wind engineering in the beginning of the 21 st century,which includes several research aspects such as the refinement to the theory of wind-induced vibration,the mechanism of wind-induced vibration,the computational fluid dynamics applications,the modification in identifying aerodynamic parameters and the wind-resistant countermeasures for super long-span bridges.Using the favorable situation of large scale bridge construction into new century,the study on bridge wind engineering in China may be expected to have a big step progress through innovative efforts and to reach the world's advanced level.
