基于大连青石洼桥的双曲拱桥加固研究

结合大连市青石洼双曲拱桥的加固设计实例,提出了双曲拱桥的有限元分析方法,将有关的荷载试验结果与理论计算值作了比较和分析,从而验证所提出的计算方法的可行性、可靠性和合理性,总结出了有限单元法的基本理论,并对其他双曲拱桥的维修加固有指导作用。

Study on hyperbolic arch bridge reinforcement of Dalian Qingshiwa Bridge

With a combination of the hyperbolic arch bridge design of Dalian Qingshiwa Bridge,it presented the finite element analysis method of hyperbolic arch bridge,compared relevant load test results with theoretical calculation values and analyzed them.Accordingly,it verified the feasibility,reliability and rationality of the proposed calculation method,summed up the basic theory of finite element method,and had some guidance for the other hyperbolic arch bridge strengthening.
