公路改扩建工程桥梁加宽方案技术研究

Research on Bridge Widening Scheme Technology for Highway Reconstruction and Expansion Project

随着国民经济收入的持续增长,汽车拥有量也大幅度增加,自驾出行频率也越来越高,随之而来的就是高速公路拥堵问题,为有效改善这一现状,就不得不对原有公路进行拓宽改造。在公路改扩建工程施工中,对老旧桥梁进行拓宽改造,桥梁结构就会出现变形现象,严重影响桥梁整体质量及使用功能。本文笔者从桥梁加宽改造原则及拓宽改造加宽方式出发,对不同结构的公路桥梁拓宽改造方案展开详细论述,希望通过本研究,能有效促进我国高速公路改扩建工程的稳定发展,使其继续助推我国经济持续增长,尽快实现中华民族伟大复兴梦。

With the continuous growth of national economic income, the number of car ownership has also increased substantially, and the frequency of self-driving travel has become higher and higher. The problem of expressway congestion is followed. To effectively improve this situation, it is necessary to expand and renovate the expressway. In the construction of highway reconstruction and expansion projects, the old bridges will be extensively modified, and the bridge structure will be deformed, which will seriously affect the overall quality and function of the bridge. In this paper, the author starts from the principle of widening the bridge and the widening way, and elaborates on the widening and reconstruction plan of highway bridges with different structures. It is hoped that through this research, the stable development of highway reconstruction and expansion projects in China can be effectively promoted, so as to promote the sustained growth of our economy and realize the great rejuvenation dream of the Chinese nation as soon as possible.
