高速公路桥梁加固施工技术
摘要:随着我国交通运输事业的快速发展,高速公路桥梁得到了大规模兴建,为我国的经济发展和社会建设做出了巨大贡献。但是随着公路桥梁运行年限的增加,不可避免会出现一些病害。为了有效提升其通行能力与安全系数,必须对于开裂、变形等病害进行加固处理,而加固施工技术的应用是否合理直接关系到施工作业的整体效率与质量。本文首先分析了高速公路桥梁进行加固的意义,然后归纳了高速公路桥梁常见的病害,最后重点从桥梁的下部架构和上部结构两方面详细探讨了高速公路桥梁加固的施工技术要点。

Abstract: with the rapid development of our country transportation enterprise, got large-scale construction of highway Bridges, for our country's economic development and made great contribution to social construction. But along with the increasing length of highway Bridges run, inevitably there will be some disease. In order to effectively improve the traffic capacity and safety coefficient, must reinforce the treatment of diseases such as crack, deformation, and strengthening the application of construction technology is reasonable is directly related to the overall efficiency of construction work and quality. At first, this paper analyzes the significance of highway Bridges strengthening, and then sums up mon deterioration problems of highway Bridges, the focus from the lower part of the bridge structure and the upper structure two aspects of highway bridge reinforcement is discussed in detail the construction technology key points.
Key words: highway Bridges; Reinforcement; Fracture; Pier; Paste the steel plate.
