Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] see figure 1 , the present invention at first provides a kind of multi-model landslide displacement prediction method, comprises the following steps:

[0024] S1: Obtain the monitoring data of landslide displacement, and process the monitoring data at equal time intervals to obtain the first displacement time series of the landslide.

[0025] The landslide displacement is not a uniformly changing value, so the monitoring data is processed at equal time intervals to obtain the displacement sequence of a certain landslide point (T 1 ,D 1 ),(T 2 ,D 2 ),...,(T i ,D i ),...,(T n ,D n ), where D i means T i The actual monitoring displacement value at any time, i=1,2,...,n.

[0026] S2: Select multiple displacement prediction models to pr...

Abstract

The invention discloses a multi-model landslide displacement prediction method and its system to solve the problems that the traditional single-model prediction accuracy is not high and the combined prediction model weight is difficult to determine. The method of the present invention comprises the following steps: obtaining landslide displacement monitoring data, and processing the monitoring data at equal time intervals to obtain the displacement time series of the landslide; selecting a plurality of displacement prediction models to predict the landslide displacement within the time range corresponding to the displacement time series to obtain Predict the displacement time series; obtain the prediction model accuracy matrix by predicting the displacement time series and the displacement time series, and determine the prediction model weight matrix according to the prediction model accuracy matrix; combine the prediction model weights with the displacement data predicted by the selected displacement prediction models matrix to get the final predicted displacement result.

Description

technical field [0001] The invention relates to the field of landslide displacement prediction, in particular to a multi-model landslide displacement prediction method and system thereof. Background technique [0002] Landslide is a frequent geological disaster, which not only destroys local resources and environment, but also seriously threatens the safety of human life and property. The geological tectonic activities in western my country are intense, and there are many types of geological disasters, especially landslides. According to statistics, an average of 700 to 900 people die every year in my country due to landslide disasters, and the direct economic loss is hundreds of billions of yuan. In order to effectively reduce the catastrophe caused by landslides, it is particularly important to monitor and predict landslide displacement. Since landslides are very complex nonlinear dynamic systems accompanied by many uncertain factors, accurate prediction of landslides ha...
