摘要本毕业设计根据设计规范的规定以及毕业设计任务书要求，参照已建桥梁设计，确定桥梁型式和结构形式。预应力混凝土简支梁桥具有结构受力性能较好、变形小等优点。简支梁桥成为最富有竞争力的桥型之一。本设计对象为装配式钢筋混凝土简支T形梁桥，施工方法选为预制T梁法，采用分离式路基，只考虑半面路基的设计，桥梁平面位于直线段上，主梁全长34.96米，桥梁宽度17.5米（半面），设计荷载为公路Ⅰ级。主梁横向由9片T梁组成，梁高均为1.8m。 42748
设计先进行恒载、活载的计算，以此为基础进行荷载组合,绘制弯矩和剪力图。最后，对该简支梁桥进行验算，是否满足设计要求。全桥采用MIDAS软件进行计算，所有设计图纸均由AutoCAD绘制，计算机排版，打印出图及计算书。此外，还翻译了一篇英文文献“基础设施实现BIM:比较两个桥梁建设项目”

Abstract The provisions of this graduation design according to the design specification and graduation design specification requirements, the reference of built bridge design, bridge type and structure form. Prestressed concrete beam bridge has the structure stress performance good, and the advantages of small deformation. Simply supported girder bridge become one of the most competitive bridge type. This design objects for the prefabricated reinforced concrete simply supported T beam bridge, the construction method is selected as the prefabricated T beam method, the separated subgrade, consider only half the design of the subgrade, bridge is located in a straight line, plane girder total length of 34.96 meters, bridge width 17.5 meters (a surface), design load for highway Ⅰ level. Transverse girder is composed of 9 pieces of the T beam, beam high of 1.8 m.Design to dead load and live load calculation, based on the load combination, draw the bending moment and shear force diagrams. Finally, calculation of the simply supported girder bridge, whether to meet the design requirements. Full bridge is calculated, using MIDAS software all design drawings by AutoCAD drawing, computer typesetting, print out the chart and calculations. In addition, an article in English translated documents "infrastructure implementation BIM: compare two bridge construction project"
Key words: simply supported bridge design prestressed precast T girder
