摘要
通过最小二乘拟合方法探讨了温度对斜拉索频率影响的规律,提出一个能有效消除温度影响的修正方法,以荷麻溪大桥的斜拉索索力测试为研究背景分析了该修正方法的可行性和实用性。
A equation filling method about temperature correction by the least square was introduced in detail and its application in real data analysis was discussed.The experiment data of Hemaxi cable-stayed bridge was used to investigate the efficiency and practicability of the method.
