摘要
面对日益增长的桥梁通行需求,既有桥梁的拼宽处理势在必行,介绍了改扩建桥梁的特点与难点,分析了不同连接方案的优缺点以及拼宽桥上下部结构形式的选择,最后以××工程实例为载体,详细的介绍了拼宽桥梁设计思路及原则在工程实例中的应用,并针对施工期间的保通提供了一个解决方案。
In the face of the growing traffic demand,existing bridge widening is imperative.This paper introduces the characteristics and difficulties of the reconstruction and expansion of bridges,analyzes the advantages and disadvantages of different splicing schemes and the selection of the upper and lower structural forms.Finally,taking an engineering example as the carrier,this paper introduces the application of the design ideas and principles of the bridge splicing in the engineering example in details,and provides a solution for maintaining traffic during the period of construction,and provide a reference for similar projects.
