1、 浑河桥设计 Design of Hun River Bridge 学 院：土木工程学院 专 业 班 级： 学 号： 学 生 姓 名： 指 导 教 师： I 摘 要 随着中国经济的腾飞，道路桥梁工程也得以迅猛发展，大力发展建通运输事 业，剪力四通八达的现代交通网络，这不仅利于经济的进一步发展，同时对促进 文化交流、加强民族团结、缩小地区差别、巩固国防等方面，也都有重要意义。 桥梁工程是一种功能性的结构物，但从古至今，人类从未停止过对桥梁美学 的追求，很多桥梁被建成为令人赏心悦目的艺术品，具有鲜明的时代特征，至今 仍然为人们所赞叹。 目前随着国家公路五纵七横国道主干线的规划和实施，几十公里长的跨

2、海 湾，海峡特大桥梁的宏伟工程已经摆在我们面前，并已逐渐开始建设，例如浙江 宁波杭州湾跨海大桥，是目前世界上最长的桥梁。 本次设计的是简支 T 形梁桥，桥梁全长 120m，道路等级一级，双向六车道。 设计主要包括方案比选、内力计算、预应力筋计算、结构强度验算、桥墩计算、 挠度与预拱度的计算。设计的基本要求是“适用、安全、耐久” 。 通过本次设计，我充分了解了土木工程方面的知识，以及桥梁建设者面临着 设计新颖和复杂桥梁结构的挑战， 所以我要更加努力的去学习有关道路桥梁方面 的知识，成为一个对国家，对社会有用的人。 关键词：道路桥梁；方案比选；内力；桥墩关键词：道路桥梁；方案比选；内力；桥墩 II

3、 Abstract As Chinas economic take-off, road and bridge project is also to the rapid development, vigorously develop Jian Tong transportation industry, shear ease of modern transportation network, which is not only conducive to the further economic development, and the promotion of cultural exchanges

4、, strengthen national unity, reduce regional differences, consolidate national defense, etc., also are important. Bridge Engineering is a functional structure, but since ancient times, mankind has never stopped the pursuit of bridge aesthetics, many bridges were built for pleasing works of art, with

5、 distinctive characteristics of the times, is still for the people praise. With the current state highway five vertical and seven horizontal national trunk road planning and implementation of dozens of kilometers across the Gulf, Strait of large bridges grand project has been placed in front of us,

6、and has gradually started building, such as Ningbo, Zhejiang Hangzhou Bay Bridge bridge, is currently the worlds longest bridge. The design of the T-shaped beam is simply supported bridge, bridge length of 120m, road grade one, two-way six lanes. Design includes Alternatives, force calculation, tendons calculation, structural strength checking, piers calculated deflection and camber calculations. Design of the basic requirements of a “suitable, safe and durable.“ Through this desig
