| 摘 要： | 为更好地评价大型桥梁的安全状况，文中分析了大型桥梁特殊的结构特点，归纳了主梁、斜拉索和索塔等不同部位的静态响应内容。针对温度、风、交通荷载等众多因素的影响，利用傅立叶变换对检测数据进行分析处理。工程实例表明，该方法具有较强的实用性和较高的准确性，能反映检测内容的实际变化规律，为桥梁结构检测提供了一个有效的途径。 |

| Abstract: | In order to evaluate the security of great bridge,combining with the structural characteristic of the great bridge,the static response monitoring of main beam,partial cable and cable tower are analyzed.Aimed at influencing factors,such as temperature,wind,traffic load and so on,Fourier analysis is used to deal with the monitoring data.The case study shows that this method has high accuracy.It is an effective method for monitoring of the great bridge structure. |
| Keywords: | great bridge static response monitoring Fourier analysis |
