摘要
以白水河滑坡时间位移序列作为研究对象,提出了用信息维来研究滑坡时间位移序列的方法。对ZG93监测点的时间序列进行了分年信息维数计算,同时对2006—2009年预警区内所有监测点时间序列进行了分维异常分析。结果表明,时间位移序列的信息维数大小与序列的频变和骤变有关;分维异常图可以反映滑坡空间范围内各部位的相对变形情况。
The objective of this study is to put forward the method of information dimension to study the landslide displacement.This study is based on the time-displacement series of Baishuihe landslide.We can analyze the fractal dimension anomaly of all GPS points from 2006 to 2009 in the warning zone by calculating the information dimension of the yearly monitoring GPS point ZG93.The results show that the size of the information dimension of time-displacement series has some relationships with its frequency-dependent and cataclysm snap.The fractal dimension anomaly map can reflect the relative deformation of the landslide at different parts from space within the scope.
