摘要
以锦州沟帮子秀水桥为例,分析大跨人行悬索桥的实用构造及计算方法,尤其是对大跨人行悬索体系空间索面的成桥线形,各阶段变形的控制,索鞍预偏量。运用空间分析的方法,准确高效地进行结构受力和变形的变化分析,保证结构受力和变形的安全合理。
Taking the Xiushui Bridge in the city of Jinzhou as an example, the article analyzes the practical construction and calculation methods of long-span pedestrian suspension bridge, especially for the cable bridge alignment space for suspension system of large span, control deformation stages, pre-bias of cable saddle. Using the spatial analysis methods, it analyzes the change of the structure force and deformation accurately and efficiently in order to ensure the safety of the structure force and deformation.
