Therefore the invention is the simple, intuitionistic, economical and high-efficient space-time prediction of the landslide catastrophe process.

Description

technical field [0001] The invention relates to a landslide spatiotemporal prediction method, in particular to an intelligent method capable of spatiotemporal prediction of landslide catastrophe process. More specifically, it is an intelligent prediction method combining geotechnical mechanics with field monitoring. Background technique [0002] my country is a landslide geological disaster-prone area, and landslides cause huge economic losses and heavy casualties to our country every year. With the continuous development of social economy, landslides, as a kind of geological disaster, have had a great impact on the lives of local residents due to their serious hazards. Although great achievements have been made in the research of landslide spatiotemporal prediction methods, a large number of landslide geological disasters still occur every year, which shows that the existing landslide spatiotemporal prediction methods still have defects. [0003] At present, there is no s...

Problems solved by technology

[0003] At present, there is no systematic method for landslide spatio-temporal prediction. The method often used in engineering practice is: first judge the stability and instability of the landslide according to the two-dimensional limit equilibrium method; decide whether to reinforce

The traditional spatio-temporal prediction methods of landslides lack theoretical basis and cannot predict the deformation of landslides, and the accuracy cannot be guaranteed

In addition, the traditional spatio-temporal prediction method of landslides uses the two-dimensional limit equilibrium method to judge the stability of landslides. In fact, landslides are a three-dimensional problem, and the two-dimensional calculation method obviously cannot reflect the real stress state of landslides; Simple processing of displacement monitoring data to judge the instability time of the landslide, this method does not consider the rheological characteristics of the landslide medium, therefore, the physical meaning is not clear

[0004] In short, the traditional space-time prediction method of landslides does not reflect the nonlinear nature of landslide rock and soil materials, and does not reflect the catastrophic process of landslides. Therefore, it is necessary to develop a method that can reflect the nonlinear nature of landslide rock and soil materials and facilitate engineering applications.
