基于G-P法和Cao法的桥梁变形时间序列最佳嵌入维数的确定

摘要

Taking a bridge as an example, the two points on Q5 and C5 deformation time series is analyzed.Tilt of Q5 point and C5 point of subsidence time series, time series using G-P algorithm and Cao algorithm are respectively calculated by the best embedding dimension.Calculated results show that the two methods results can verify each other, proved their reliability.%以某大桥为例,对其上两个点Q5和C5的变形时间序列进行了分析.对Q5点的倾斜时间序列和C5点的沉降时间序列,运用G-P算法和Cao算法分别计算了它们的最佳嵌入维数.计算结果表明,这两种方法得出的结果可以互相验证,证明了它们的可靠性.
