The invention provides a
landslide displacement multilinear prediction method based on an ST-SEEP segmentation method and a space-time ARMA model. The
landslide displacement multilinear prediction method comprises the steps of data preprocessing, curve segmentation, spatial weight matrix acquisition, modeling and prediction, and prediction effect evaluation. in data preprocessing step, reading
landslide displacement data and coordinate data, and preprocessing the landslide displacement data and the coordinate data; drawing a landslide displacement-
time curve in a curve segmentation mode, and providing an ST-SEEP method to conduct segmentation
processing on the curve; in spatial weight matrix acquisition step, performing
spatial clustering on the monitoring points by adopting a K-means clustering method, and acquiring a spatial weight matrix; modeling and predicting to establish a space-time ARMA model, and predicting a landslide displacement space-
time sequence; and the prediction result evaluation adopting an absolute error and a root-mean-
square error to evaluate the prediction result. The method has the beneficial effects that quantitative analysis of the
spatial relationship of the monitoring points is realized, and the
spatial relationship is more effectively utilized; the space-time autoregressive
moving average statistical model is introduced into the landslide prediction field, the physical significance of formulas and parameters is clear, the process is clear, and the landslide displacement can be accurately predicted.
