【摘要】：拱桥为桥梁家族的重要成员，，一直占据着不可或缺的地位。飞燕式钢管砼异型拱桥具有优美造型、方便多样的施工、跨越能力大等优点，是城市桥梁中一种颇具竞争力的新颖桥型。本文以长春市伊通河飞燕式钢管砼异型拱桥为研究对象，从桥型方案比选、桥梁结构设计、桥梁静力分析、桥梁抗震设计分析等四个方面进行分析计算。本论文完成的主要工作为：（1）针对102国道跨伊通河桥梁工程的地理位置、建设条件，对大桥的桥型方案进行了比选，最终确定为飞燕式异型钢管混凝土拱桥方案。（2）通过方案比较及尺寸的拟定，研究结构的受力特性，合理选择结构尺寸，在满足结构安全的前提下，使大桥更经济、合理、美观。（3）利用有限元计算软件Midas/Civil，对该桥梁的设计应力、承载能力以及变形进行分析静力分析，分析计算结果满足设计规范要求。（4）利用有限元计算软件SAP2000，分析主桥在50年10％概率（E1）和50年2％概率（E2）下地震反应谱响应，给出以下桥梁结构关键部位的地震反应谱响应结果。
[Abstract]:As an important member of bridge family, arch bridge has always occupied an indispensable position. Feiyan shaped concrete-filled steel tubular arch bridge has the advantages of graceful shape, convenient construction and large span capacity. It is a new type of bridge in urban bridges. This paper takes the Yitong River Feiyan shaped concrete-filled steel tube arch bridge in Changchun as the research object. The analysis and calculation are carried out from four aspects: bridge scheme comparison, bridge structure design, bridge static analysis and bridge seismic design analysis. The main work of this thesis is as follows: 1) aiming at the geographical position and construction conditions of the 102 national highway bridge project across Yitong River, the bridge type scheme of the bridge is compared and selected, and the scheme of Feiyan shaped concrete-filled steel tube arch bridge is finally determined. 2) by comparing the scheme and drawing up the dimensions, the stress characteristics of the structure are studied, and the structural dimensions are reasonably selected. On the premise of satisfying the safety of the structure, the bridge is made more economical, reasonable and beautiful. 3) the design stress, bearing capacity and deformation of the bridge are analyzed by the finite element calculation software Midas / Civil, and the results meet the requirements of the design code. 4) using finite element software SAP2000, the seismic response spectrum response of the main bridge under 50 years (10% probabilistic E _ 1) and 50 years (2% probability E _ 2) is analyzed, and the seismic response spectrum response results of the following key parts of the bridge structure are given.
