【摘要】 以自锚式悬索桥为研究对象,采用有限元方法对自锚式混凝土悬索桥进行动力特性分析,并通过实桥环境随机振动试验验证有限元动力特性分析结果,得到了此类小跨径独塔自锚式悬索桥的动力特性,为该桥运营阶段的健康诊断与损伤识别提供了基本依据。更多还原

【Abstract】 The paper chose an in-use self-anchored concrete suspension bridge as the object of study and introduced finite element method to analyse its dynamic performance.In the hope of verifying the results arrived,random ambient vibration test was conducted.By this means,the dynamic performance of the small-span self-anchored suspension bridge with single pylon was concluded,which provided a rough reference for quality monitoring and defect diagnosis.更多还原
