本文简要介绍了近代桥梁设计理论和风洞实验的相关结果,并针对空气流体与桥梁表面的受力关系进行深入讨论。通过分析早年设计桥梁失败的经典案例,总结了空气流体对桥梁造成损害的几种机制。文章主要研究空气流体对于桥梁的作用,这里针对大连星海湾大桥的横截面,细致推导了相关的受力分析,并提出了可行的改进方案。
This paper briefly introduces the modern bridge design theory and wind tunnel experiment results, and discusses the relationship between the air fluid and the bridge surface force. By analyzing the classic case of bridge failure in the early years of design, several mechanisms of air fluid damage to the bridge were summarized. This paper mainly studies the effect of air fluid on the bridge. For the cross section of Dalian Xinghai Bay Bridge, the relevant stress analysis is deduced carefully and the feasible improvement scheme is proposed.
