预应力混凝土简支T梁桥设计
大连星海大桥T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。
