摘要
通过最小二乘拟合方法寻找斜拉索索力与频率的对应关系,讨论了这些关系在频率法测量索力中的应用,并在此基础上,以某大桥的斜拉桥索力测试为研究背景,分析了该方法的可行性和实用性。
A nonlinear equation fitting method by the least square was introduced in detail and its application in real data analysis.was discussed. The experiment data of a cable-stayed bridge was used to investigate the efficiency and practicability of the method.
