    毕设基本摘要

    摘要
    在本设计中,根据地形图和任务书要求,依据现行公路桥梁设计规范提出了预应力混凝土连续梁桥、斜拉桥、中承式拱桥三种桥型方案。按照“实用、经济、安全、美观”的桥梁设计原则,经过对各种桥型的比选最终选择35m+50m+35m的预应力混凝土连续梁桥为本次的推荐设计桥型。
    本设计是一联三跨连续梁桥,截面形式为单箱三室,纵向变截面;施工方式是满堂支架整体现浇。设计主要进行预应力混凝土连续梁桥的上部结构设计,设计中主要进行了桥梁总体布置及结构尺寸拟定、桥梁荷载内力计算、桥梁预应力钢束的估算与布置、桥梁预应力损失及应力的验算、次内力的验算、内力组合验算、主梁截面应力验算。
    在设计过程中,使用了Madis Civil、CAD、Office等软件。利用Madis Civil软件进行结构分析,根据桥梁的尺寸拟定建立桥梁有限元模型,然后进行内力分析,计算配筋结果,进行施工各阶段分析及截面验算。同时,必须要考虑混凝土收缩、徐变次内力和温度次内力等因素的影响。
    最后,编制设计计算说明书及文档整理。

    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.
