摘　　要：尼尔森吊杆体系系杆拱桥因具有良好的刚度而在近年来的高速铁路建设中得以广泛采用。由于这类桥梁常作为跨越繁忙运输通道的桥型选择方案,且桥梁的施工工期一般较紧,同时对施工安全及运输通道的防护性要求较高,因而施工控制工作十分必要。文章以某跨径为96 m的常见尼尔森吊杆体系系杆拱桥为例,对施工过程中的应力和线形进行了模拟分析,对同类桥梁的施工具有一定的指导意义。Nielsen suspender system tied arch bridge has been widely used in high-speed railway construction in recent years due to its good stiffness. Since this type of bridges are often used as bridge type selection schemes for crossing busy transportation channels, and the construction period of the bridges is generally tight, as well as the requirements for construction safety and transportation channel protection are relatively high, the construction control work is very necessary. Taking a common Nelson suspender system tied arch bridge with a span of 96 m as an example, this paper simulates and analyzes the stress and alignment during construction, which has certain guiding significance for the construction of similar bridges.
