摘要
通过对湛江海湾大桥斜拉索索力监控的研究,提出了用最小二乘法以及非线性分析来确定斜拉索的基频,通过对拉索测试试验数据的处理,找到这些数据的变化规律和理想的线性方程,实桥的测试结果表明,该方法行之有效,值得推广。
Through research of slanting bridge force controlling in Zhanjiang Bay Bridge, it brings forward basic frequency by mini dual-multiplication and lined analysis. Through the arrangement of testing data, it finds out the changing law of data and desirable lined equation. The testing result indicates, this method is effective and worth of spreading.
