摘要
以贵州盐津河大桥为研究对象,结合大跨度桁式组合拱桥的动力特性测试数据,利用ANASYS的动力分析模块,分别计算了桥梁在设计理想状态和计入损伤两种情况下盐津河大桥的动力特性,分析了结构损伤对桁式组合拱桥动力特性的影响.
Based on the dynamic test of Yanjin river bridge in Guizhou province,the paper calculates the dynamic charecteristics of long-span trussed combination arch bridge with damage and without damage,and analyzes the effect of the damage of the structure on the dynamic charecteristics of trussed combination arch bridge.
