北京知鱼桥预应力混凝土简支 T 型梁桥设计摘要桥是跨越障碍的通道,随着我国城市建设和高等级公路、道路建设的发展, 桥梁的建设也将成为必然的趋势。预应力混凝土简支 T型梁桥设计在我国公路上修建很多。本毕业设计内容为预应力混凝土简支 T型梁桥设计,结构设计包括对预应力混凝土简支 T型梁、墩柱及盖梁的设计和计算,具体计算方法包括荷载横向分布系数计算法、容许应力法。施工组织包括钻孔桩施工、 T型梁的预制和架设、支座和伸缩缝施工、以及桥面铺装和栏杆施工以及附属结构的施工等。设计中参考了《桥梁计算示例集—混凝土简支梁(板)桥》、《公路钢筋混凝土及预应力桥涵设计规范》、《公路桥涵设计通用规范》、《桥梁工程》、《桥梁施工组织管理》等课内外有关资料。关键词:预应力,混凝土 T梁 Abstract Bridge across obstacles corridors, with our urban construction and the high-grade highway, road construction, bridge building will also e the inevitable trend. Pre-stressed Concrete T bridge design teams in the construction of many ofour roads. The design elements for Pre-stressed Concrete graduated from T bridge design, structural design, including extensions of Pre-stressed Concrete, and culvert design and calculation, the specific methodology including horizontal distribution of load factor calculations, allowing stress law. anizations, including bored pile construction, and erection of prefabricated T bridge design, secure and joints construction, decking and railings and deck construction and construction subsidiary structure. Specific reference in the design of the "bridge of examples Collection - concrete extensions (board) Bridge," and "Highway design of reinforced concrete and pre-stressed norms", "road tunnels designed generic norms", "bridge project", "bridge anization and management" classes and outside information.
