Example Embodiment

[0026] Embodiment one

[0027] figure 1 It is a flow chart of a landslide prediction method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of evaluating the susceptibility of landslides. The method can be executed by a landslide prediction device, such as figure 1 As shown, the method includes the following steps:

[0028] S110. Acquiring daily landslide impact factors within a set period of time for each slope unit in the target area.

[0029] Among them, the target area is usually the area where the landslide has occurred, and it can also be any designated area. The slope unit is the basic unit for the development of geological hazards such as landslides and collapses, and each unit is given a corresponding attribute value to represent a data form of the entity. The set time period may be one day, three days, one week, one month or other time periods before the day when the landslide occurs.

[0030] Wherein, the landsli...

Abstract

The embodiment of the invention discloses a landslide prediction method and device, equipment and a storage medium. The method comprises the following steps: obtaining landslide influence factors of each slope unit in a target area every day in a set time period, wherein the landslide influence factors comprise a dynamic factor and a static factor; determining a dynamic probability value of landslide of each slope unit based on the dynamic factors; and determining a static probability value of landslide of each slope unit based on the static factor, and separately performing landslide prediction on the dynamic factor and the static factor, so that the missing report rate and the false alarm rate in the landslide prediction process can be reduced. The landslide occurrence probability of thetarget area is obtained according to the dynamic probability value and the static probability value, the corresponding probability values of the two types of landslide influence factors are integrated for combined prediction, landslide prediction is carried out by combining the characteristics of the two types of landslide influence factors, and the prediction precision of landslide can be further improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of landslide monitoring, in particular to a landslide prediction method, device, equipment and storage medium. Background technique [0002] Landslides are one of the most common catastrophic natural disasters, which have the characteristics of wide distribution, high frequency of occurrence, multiple, regional and serious, because landslides cause a large number of casualties and major environmental and infrastructure damage every year loss. It is of great significance to evaluate the susceptibility of landslides. [0003] The existing landslide susceptibility prediction can be divided into deterministic methods and non-deterministic methods according to the difference of their theoretical basis. Deterministic methods are mainly directional analysis based on expert experience and knowledge and methods based on landslide process or physical models, and the prediction accuracy is p...
