Slope stability monitoring and early warning method and system and medium

Abstract

The invention belongs to the technical field of slope monitoring and early warning, and discloses a slope stability monitoring and early warning method and system and a medium. The method comprises the steps: detecting slope data and preprocessing the detection data; using a qualitative analysis and quantitative analysis method for analysis and judgment according to the slope deformation evolutionstage, the slope displacement vector angle, the slope displacement rate angle, the slope displacement azimuth angle and the slope body crack distribution condition; summarizing a deformation space-time evolution rule, deformation space-time characteristics and a deformation instability failure mode of the slope; establishing multi-parameter early warning criteria of an attention level (blue), a warning level (yellow), a warning level (orange) and a forecasting level (red) according to an analysis result; and developing a slope instability damage early warning program, and carrying out dynamiccomprehensive early warning on slope deformation instability damage. The application of the method in the slope of the open pit mine of the pointed mountain shows that the method plays a role in ensuring the safety production of the open pit mine of the pointed mountain, and can be popularized and applied in slope monitoring engineering with similar conditions.

Description

technical field [0001] The invention belongs to the technical field of slope monitoring and early warning, and in particular relates to a slope stability monitoring and early warning method, system and medium. Background technique [0002] At present, with the continuous and high-intensity mining of phosphate rock resources, many large state-owned phosphate mines in my country have gradually transferred to the deep concave open-pit mining or underground mining stage. With the continuous increase in the intensity of mining activities, safety issues related to mining production have become more and more prominent, and have increasingly become a bottleneck restricting the safety and sustainable development of enterprises. After the beneficiation method is changed from scrubbing to flotation, the tailings particles will be finer. At this time, the consolidation characteristics of the tailings will change significantly. How to ensure the stability of the tailings dam will play a ...

AI Technical Summary

Problems solved by technology

[0004] (1) During the automatic monitoring process of traditional technology, due to some objective environmental factors (such as rain and fog weather) and the instrument itself, the collected monitoring data may have singular values, or some monitoring points may be missed. , or no measurement data for a certain period of time

[0005] (2) The traditional analysis method only considers the magnitude of the displacement or the displacement rate, and there is no comprehensive analysis of the slip direction of the monitoring point. This analysis method is not comprehensive.

Lack of existing empirical methods that can be used for reference
