摘　　要：斜拉桥模式在沉寂一段时间之后以其独特的优势进入了人们的视野。由于地震波对斜拉桥的影响较大,因此,大跨度斜拉桥对抗震能力有比较高的要求。论文以有限元建模的方法对某工程项目中的斜拉桥实体进行建模,并采用子空间迭代法进行了桥体关键部位抗震能力分析,以期为工程应用提供理论指导。After a period of silence,cable-stayed bridge mode has entered people's vision with its unique advantages.The long-span cable-stayed bridge has a higher requirement for seismic capacity,because the seismic wave has a greater impact on the cable-stayed bridge.In this paper,the finite element modeling method is used to model the cable-stayed bridge entity in a project,and the subspace iteration method is used to analyze the seismic capacity ofkey parts of the bridge,in order to provide theoretical guidance for engineering application.

关 键 词：大跨度斜拉桥 抗震能力 有限元建模 子空间迭代法
