【摘要】：拱橋?yàn)闃蛄杭易宓闹匾蓡T，，一直占據(jù)著不可或缺的地位。飛燕式鋼管砼異型拱橋具有優(yōu)美造型、方便多樣的施工、跨越能力大等優(yōu)點(diǎn)，是城市橋梁中一種頗具競(jìng)爭(zhēng)力的新穎橋型。本文以長(zhǎng)春市伊通河飛燕式鋼管砼異型拱橋?yàn)檠芯繉?duì)象，從橋型方案比選、橋梁結(jié)構(gòu)設(shè)計(jì)、橋梁靜力分析、橋梁抗震設(shè)計(jì)分析等四個(gè)方面進(jìn)行分析計(jì)算。本論文完成的主要工作為： （1）針對(duì)102國道跨伊通河橋梁工程的地理位置、建設(shè)條件，對(duì)大橋的橋型方案進(jìn)行了比選，最終確定為飛燕式異型鋼管混凝土拱橋方案。 （2）通過方案比較及尺寸的擬定，研究結(jié)構(gòu)的受力特性，合理選擇結(jié)構(gòu)尺寸，在滿足結(jié)構(gòu)安全的前提下，使大橋更經(jīng)濟(jì)、合理、美觀。 （3）利用有限元計(jì)算軟件Midas/Civil，對(duì)該橋梁的設(shè)計(jì)應(yīng)力、承載能力以及變形進(jìn)行分析靜力分析，分析計(jì)算結(jié)果滿足設(shè)計(jì)規(guī)范要求。 （4）利用有限元計(jì)算軟件SAP2000，分析主橋在50年10％概率（E1）和50年2％概率（E2）下地震反應(yīng)譜響應(yīng)，給出以下橋梁結(jié)構(gòu)關(guān)鍵部位的地震反應(yīng)譜響應(yīng)結(jié)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.
