1、 .1. 毕 业 论 文（设 计） 2013 届 土木工程 专业 0909052 班级 题题 目目 京港澳高速跨河 16 米预应力空心板桥设 计 二 0 一三年 五 月月 二十三日日 .2. 京港澳高速跨河 16m 预应力混凝土空心板桥计 内内 容容 提提 要要 预应力混凝土空心板桥在我国桥梁建筑上占我重要的地位， 在目前对 于中小跨径的永久性桥梁，无论是公路桥梁或者城市桥梁，都在尽量采用 预应力混凝土空心板桥，因为这种桥梁具有就地取材，工业化施工，耐久 性好，适应性强，整体性好以等多种优点，从而决定了本设计中桥型的选 择，整个计算的方法。该桥地处京港澳高速文峰大道上，是一级公路上的 一座桥梁

2、，单跨 16 米，地质情况较好，公路中央分割带为 5 米，故设计 为分幅式,设计中首先确定桥的类型，构造的设计，梁板布置的选择和定 位，本桥采用的是装配式预应力混凝土简支空心板梁桥， 其次根据已定的 结构设计和计算配筋。其中包括截面尺寸，计算简图的确定，计算方法， 荷载计算，内力计算并绘制内力图，影响线等。下部结构设计中，确定为 埋置式刚性扩大基础桥台设计，进行了基础的验算，满足了设计要求。最 后使用 CAD 制图将所设计的构造和配筋进行说明。 关键词关键词 跨径跨径; ;分幅式分幅式; ;空心板空心板; ;预应力预应力 .3. 16m Prestressed Concrete Hollow

3、Slab Design Abstract Pestressed concrete hollow slab bridge in China on the bridge architecture of my important position, for the moment, for small and medium-sized span of the permanent bridge, whether the highway bridge or city Bridges, as far as possible in the prestressed concrete hollow slab br

4、idge, because this bridge has use local materials, industrial construction, good durability, strong adaptability, integral sex is good and so on many kinds of advantages, to decide the design in the choice of the form, the whole calculationmethod. The bridge is located in Beijing Hong Kong and Macao

5、 high-speed Wenfeng Avenue., is one of a bridge on the road, single-span of 16 metres, good geological conditions, the split with the central highway to three meters, is designed tosub-sites. This design is divided into the upper structure design. The lower part of the structure and design of two ma

6、jor parts. Superstructure design, first determine the type ofbridge, structural design, the choice of beam layout and positioning, the bridge is used in assembly-prestressed concrete simple hollow plate girder bridge, followed has been set in accordance with the structural design and calculation with Tendons. Including the section size, the calculation of the sketch identified, calculation methods, load, the .4. calculation of internal forces and internal 11forces drawn map, influence
