摘要
本设计是根据设计任务书的要求和《公路桥规》的规定，选定装配式预应力T形截面简支梁桥。该类型的梁桥具有受力均匀、稳定，且对于小跨径单跨不产生负弯矩，施工简单进度快且整体性好、接头方便等优点，而且能有效的利用现代高强材料，减少构件截面，与钢筋混凝土相比，能节省钢材，且在荷载的作用下不会出现裂缝，基础施工项目较少。本文通过对国内外相关文献的查阅与整理，总结出我对预应力混凝土简支T梁桥的一些认识。再者经过一座桥梁从方案倒施工图全部设计过程，还能掌握对文献的检索与调研能力、与相关专业人员的配合与协调能力、制定设计方案并进行比选的能力、编写设计说明书的能力、运用专业计算机软件进行施工图绘制及运用专业计算机软件进行预应力混凝土简支 T 梁桥设计的能力。

ABSTRACT
This design is based on the requirements of the design specification and the provisions of the highway bridge regulations, the prestressing T-section bridge is selected. Uniformity and stability of this type of bridge with force, and for the small single span does not produce negative bending moment, simple construction progress fast and good entirety, convenient connection, and effective use of modern high strength materials, reduce the components section, compared with reinforced concrete, can save steel, and under the action of load will not crack, less foundation construction project. Through the review and arrangement of the related literature at home and abroad, this paper summarizes my understanding of prestressed concrete simply supported T beam bridge. Again after a bridge from plan to pour all construction drawing design process, also can master of literature retrieval and research ability, and related professional cooperation and coordination, set design and comparison of ability, the ability to write design specifications, using specialized computer software to carry on the construction drawings and use specialized computer software for prestressed concrete simply supported T beam bridge design ability.
Key words：Prestressed concrete simply supported T beam bridge、Construction drawing、software drawing
