位于皖苏交界处的滁河大桥由于其特殊的地理环境和所在滁河航道规划等级的变化,作为沪陕G40高速改扩建工程中的一个控制性工程,改扩建时其方案对整个项目的实施方案有着至关重要的影响。因此本文结合沪陕高速改扩建工程可行性研究报告,对滁河大桥改扩建设计方案进行了深入的研究。研究过程中采用的“老桥老标准、新桥新标准”的思路对于其它类似工程设计方案的研究有一定的参考价值。 As the control project of Shanghai-Shaanxi G40 high-speed reconstruction and expansion project, Chuhe Bridge located at the junction of Anhui-Jiangsu, due to its special geographical environment and the grade of Chuhe Channel planning, is under its control over the entire project The program has a crucial impact. Therefore, this article combined with the feasibility study report of the reconstruction project of Shanghai-Shaanxi Expressway to conduct an in-depth research on the design plan of Chuhe Bridge’s reconstruction and expansion. The research method used in the “Old Bridge standards, Newbridge new standards,” the idea of ​​other similar engineering design program has some reference value.
