Intelligent geological disaster risk analysis method

Abstract

The invention discloses an intelligent geological disaster risk analysis method, comprising S100, establishing an ArcGIS independent database of the cloud under the monitoring network, and establishing a unified data interaction language, S200, collecting and integrates regional geological data through a data integration program, and forming a data dictionary description of the data, uploading thedata dictionary description of the data to the ArcGIS independent database through a data integration system, and backing up the data to an emergency database, S300, performing single factor analysis, multiple factor analysis and multi-information mixed factor analysis moduling through ArcGIS, and forming an information volume model, and S400, building a data analysis model program in a GIS database, forming a multi-level data analysis layer, and displaying data on an ArcGIS platform. The intelligent geological disaster risk analysis method provides more effective and intelligent data integration and data analysis, and therefore a more specific risk analysis result is obtained.

Description

technical field [0001] The invention relates to the field of geological disasters, in particular to an intelligent geological disaster risk analysis method. Background technique [0002] Geological disasters refer to disastrous geological events formed by various geological processes during the development and evolution of the earth. The distribution and change of geological disasters in time and space are not only restricted by the natural environment, but also related to human activities. As a result of the interaction between human beings and nature, natural disasters mainly caused by geological dynamic activities or abnormal changes in the geological environment. Deformation, displacement, and abnormal changes in the environment are phenomena or processes that endanger human life and property, life and economic activities, or destroy the resources and environment on which human beings rely for survival and development. Unfavorable geological phenomena are usually called ...

Problems solved by technology

[0003] Such as collapse, landslide, debris flow, ground fissure, ground subsidence, ground subsidence, rock burst, tunnel water inrush, mud outburst, gas outburst, coal seam spontaneous combustion, loess subsidence, rock and soil expansion, sand liquefaction, land freeze-thaw, water and soil erosion , land desertification and swamp, soil salinization, and earthquakes, volcanoes, geothermal damage, and geological disasters are natural disasters that are mainly caused by geological dynamic activities or abnormal changes in the geological environment. Under the circumstances, abnormal energy release, material movement, deformation and displacement of rock and soil mass, and abnormal environmental changes occur on the earth, which endanger human life and property, life and economic activities, or destroy the resources and environment on which human beings rely for survival and development. The timely early warning of geological disasters can reduce the loss of life and property when people encounter geological disasters. However, the current prediction of geological disasters still lacks certain accuracy and reliability. Most of the existing geological disasters in the analysis structure Based on the real-time geological collection and the comprehensive analysis of historical data, the possible risk analysis of geological disaster areas is obtained, and the analysis process is not intelligent and convenient enough. The data statistics and calculation amount of a single database are greatly increased, which affects the The accuracy of the actual calculation amount, thus resulting in a larger actual probability of geological disasters and the influence of judgment errors on geological disaster control factors
