摘　　要：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。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.
