    畢設基本摘要

    摘要
    在本設計中,根據地形圖和任務書要求,依據現行公路橋梁設計規范提出了預應力混凝土連續梁橋、斜拉橋、中承式拱橋三種橋型方案。按照“實用、經濟、安全、美觀”的橋梁設計原則,經過對各種橋型的比選最終選擇35m+50m+35m的預應力混凝土連續梁橋為本次的推薦設計橋型。
    本設計是一聯三跨連續梁橋,截面形式為單箱三室,縱向變截面;施工方式是滿堂支架整體現澆。設計主要進行預應力混凝土連續梁橋的上部結構設計,設計中主要進行了橋梁總體布置及結構尺寸擬定、橋梁荷載內力計算、橋梁預應力鋼束的估算與布置、橋梁預應力損失及應力的驗算、次內力的驗算、內力組合驗算、主梁截面應力驗算。
    在設計過程中,使用了Madis Civil、CAD、Office等軟件。利用Madis Civil軟件進行結構分析,根據橋梁的尺寸擬定建立橋梁有限元模型,然后進行內力分析,計算配筋結果,進行施工各階段分析及截面驗算。同時,必須要考慮混凝土收縮、徐變次內力和溫度次內力等因素的影響。
    最后,編制設計計算說明書及文檔整理。
    【關鍵詞】: 預應力混凝土連續梁橋;滿堂支架施工;Madis Civil;內力分析;預應力損失;次內力。

    Abstract
    In this design, according to the topography and the task book requirements according to the current highway bridge design code is proposed for prestressed concrete continuous beam bridge, cable-stayed bridge, through three bridge type arch bridge.According to the "practical, safe, economic and beautiful" principles of bridge design, through the comparison of all kinds of bridge ultimate choice 50 m + 35 m + 35 m of prestressed concrete continuous girder bridge design bridge for the recommendation.
    This design is a three span continuous girder bridge, cross section form for the single box 3 rooms, longitudinal variable cross-section; Is full framing integral cast-in-place construction way. Design of prestressed concrete continuous girder bridge of the upper structure design, design of main bridge has carried on the overall arrangement and structure size for bridge, bridge load internal force calculation, estimation of prestressed steel beam and the bridge layout, loss of prestress and the stress of checking and calculating the internal force, internal force combination checking, girder section stress checking.
    In the design process, the use of the Madis injured, CAD, Office software, etc. Using Madis Civil structure analysis software, according to the size of the bridge to bridge finite element model is established, then the internal force analysis and calculation of reinforcement as a result, carries on the analysis in each stage of construction and cross section calculation. At the same time, must want to consider the concrete shrinkage, creep, internal force and internal force. The influence of such factors as temperature time
    Finally, the preparation of design and calculation specification and document filing.
    【 key words 】 : prestressed concrete continuous girder bridge; Full framing construction; Madis injured; The internal force analysis; Loss of prestress; The internal forces.
