| 摘 要： | 以独塔斜拉桥为研究对象,通过对桥梁结构的外观检测、斜拉索内力测量和结构动、静载试验,并结合有限元模型修正,评定桥梁结构的健康状态和承载能力.结果表明:由于施工过程中斜拉索内力配置的不合理性,改变了原有结构的受力状态,是该桥病害产生的主要成因. |
| 关 键 词： | 斜拉桥 索力测量 荷载试验 承载能力 |

| Abstract: | The thesis takes a single-tower cable-stayed bridge as an example,by means of structural detection,measurement of cable tension,loading test and combined with finite-element model modification method,reasonably evaluates the cable-stayed bridge's health situation and load-bearing capacity,then puts forward the reason resulting in the main disease of the bridge is unreasonable cable tension during construction which caused stress redistribution of the original structure,and then provides credible basis for b... |
| Keywords: | cable-stayed bridge measurement of cable tension loading test load-bearing capacity |
