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.
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 disciplinarian and inherent idiosyncrasy of dynamic change of displacement of road slope.
