| 摘 要： | 斜拉桥斜索索力可以使用振动法通过检测索的自振频率来推算，但温度、雨雪以及风等环境因素对索频也都有一定的影响。为了提高检测索频的精确度，根据跟踪检测铜陵长江大桥的资料，总结出斜拉桥斜索频率受环境因素影响的变化幅度，从而更准确地了解频率测试的误差范围

| Abstract: | The cable forces of a cable stayed bridge can be estimated from measured natural frequencies by vibration method. Therefore, natural frequencies of a cable are influenced by climatic variations such as temperature, rain, snow and wind. On the basis of the measurement on the Changjiang River Bridge in Tongling the extent of error of the natural frequencies are obtained, so that the accuracy of the measurements of the natural frequencies are improved. |
