城市桥梁拼宽设计方法研究

Studies on Splicing-widening Design Methods of Urban Bridges

城市桥梁作为跨越障碍的主要结构,其拼宽设计的改建工作是公路改扩建工程的重点和难点。文章结合工程实例,探讨桥梁拼宽设计的方法及注意事项。

Urban bridge is the main structure across the barriers,thus the reconstruction work of its splicing-widening design is important and difficult work in highway expansion and reconstruction project.Combining the engineering example,this article discussed the methods of bridge splicing-widening de-sign as well as the precautions.
