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 The cable tension of the cable-stayed bridge can be estimated by using the vibration method to test the natural frequency of the cable. However, environmental factors such as temperature, rain, snow and wind also affect the cable frequency. In order to improve the accuracy of the detection of the frequency of the cable, based on the follow-up inspection of the data of Tongling Yangtze River Bridge, the variation range of the cable-stayed bridge cable slope affected by environmental factors is concluded, so as to understand the error range of the frequency test more accurately
