学号：14112601012毕业设计(论文)题目：临港新区象骨二桥施工图设计作者： 届别：2015届院 别：土建学院专业：土木工程指导老师： 职称：讲师完成时间：2015年5月摘要岳阳市临港新区象骨二桥，桥梁全长121米，桥宽20.6米。经过方案比选，将此桥设计成3跨跨径35米的装配式预应力简支T梁桥。每跨采用9片T梁，桥面设置双向4车道，车道总宽16米，两侧各设置2米人行道和0.3米栏杆。其中，设计的内容主要包括：方案比选、内力计算、预应力钢筋计算、下部结构计算、施工图绘制五部分。计算部分采用手算与电算相结合，图纸采用AutoCAD进行绘制。象骨二桥位于一条城市道路上，设计时，不仅需要考虑承载力、经济型方面问题，还要充分考虑美观性及其附属设施的重要性。在设计过程中，既要运用课本所学知识，也要熟悉和使用最新国家规范，如《公路桥涵设计通用规范》、《预应力混凝土用钢绞线》、《公路钢筋混凝土及预应力混凝土桥涵设计规范》、《城市桥梁设计规范》等。关键词：T梁；内力计算；预应力；规范。AbstractThe design of a bridge at Lingang new Area of Yue Yang is 121meters long and 20.6 meters wide. After the comparison of schemes, this bridge?is designed to be assembled prestressed concrete simply?supported T Beam Bridge?of 3?spans and each span is 35 meters long. Each cross?using 9 pieces of T?beams. Its bridge floor is designed to be four-lane of two-way. The total width of lane is 16 meters. There are two-meter-wide sidewalk and 0.3 meters wide railing on both sides of the lane. Among them,?the design content mainly includes scheme comparison、Internal force calculation、prestressed reinforcement?calculation、Substructure calculation and The construction drawing. The Calculation part is solved by hand combined with?computer and drawings drawn by AutoCAD. The bridge is located on?a?city?on the road.So, I not only need to consider the bearing capacity, economic issues, but also give full consideration to the importance of aesthetics and its affiliated facilitieswhen the design. Andnot only textbookknowledge be used, but should be familiar with?and use the latest national Specification ,Such as General Code for Design of Highway Bridges and Culverts, Steel Strand for Prestressed Concrete, Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts Code for Design of the Municipal Bridge and so on.Key Words：T-beam；Calculation of Internal Forces ；Prestressed ；Specification第一章 绪论毕业设计是专业理论知识灵活运用于工程设计实践的一次升华，是大学学习的闭幕。毕业设计是大学本科教育培养目标实现的重要阶段，是毕业前的综合学习阶段，是深化、拓展、综合教与学的重要过程，是对大学期间所
