Abstract

The invention provides a landslide displacement prediction method and device, and a storage medium. The landslide displacement prediction method comprises the following steps: obtaining historical monitoring data of landslide deformation induction factors and landslide displacement in a preset time as samples; establishing a neural network quantile regression model to obtain landslide displacementprediction results y of the m neural network quantile regression base learners; utilizing a kernel density estimation method to obtain a probability distribution function of a landslide displacementprediction result; and taking the probability distribution function as a weight, and obtaining a final combined prediction value of the landslide displacement through weighted average. The technical scheme provided by the invention has the beneficial effects that by utilizing conditional quantiles, the probability density function of each landslide displacement is obtained through a kernel densityestimation method, the final combined prediction value of the landslide displacement is obtained through weighted average, multiple prediction models can be subjected to weighted combination, the combined prediction model can eliminate large deviation generated by a single prediction model, and the reliability and precision of landslide displacement prediction are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of landslide displacement prediction, in particular to a landslide displacement prediction method, equipment and storage medium. Background technique [0002] Landslide is a kind of extremely destructive geological disaster, which is widely distributed all over the world. At present, landslide disaster has become one of the types of geological disasters with the highest frequency and the greatest loss. The prediction of landslide displacement can predict the future development trend of landslide deformation, which is of great significance to disaster prevention and mitigation, and is one of the basic tasks of landslide disaster prevention and control. [0003] In 1965, Japanese scholar Ditaka Saito put forward the classic theory of landslide time prediction based on strain rate based on laboratory test data. Since then, landslide prediction has attracted widespread attention from scholars at home and abroad,...
