在美国乃至全世界,开合桥都是重要的交通运输基础设施。一些开合桥的使用寿命已长达60年至100年,且仍保持良好状态。在继续建造新的开合桥的同时,也必须对现有的开合桥进行修复、翻新和升级改造以满足当前交通运输的需求。从开合桥的设计分析到包括结构工程、机械工程和电气工程在内的整个施工阶段,工程师们在每个阶段都要面对独特的挑战。
Opening and closing bridges are important transport infrastructure in the United States and throughout the world. Some open-close bridges have a useful life span of 60 to 100 years and remain in good condition. While continuing to construct new open and close bridges, existing open and close bridges must also be repaired, refurbished and upgraded to meet current transport needs. From the design and analysis of bridges and bridges to the entire construction phase including structural engineering, mechanical engineering and electrical engineering, engineers face unique challenges at every stage.
