| 摘 要： | 根据高速公路边坡位移动态变化时间序列的非线性性质,利用时间序列的 Takens 相空间重构方法,由一维的单变量观测数据序列进行相空间拓展,在拓展的相空间中得出公路边坡位移动态变化时间序列的分维数,从而揭示了边坡位移动态变化的内在规律及其本质特征。

| Abstract: | According to the nonlinear characteristics of displacement-time series of express road slope,phase space has been topologized from one dimension single variable time series based on Takens' phase space reconstruction,The fractal dimension of displacement-time series is acquired in reconstructed phase space,the results reveals intrinsic disciolinarian and inherent idiosyncrasy of dynamic change of displacement of road slope. |
