Description

An Intelligent Geological Disaster Comprehensive Monitoring System and Multi-level Forecasting and Analysis Method

technical field

The invention belongs to the technical field of physical automatic control, in particular to an intelligent geological disaster comprehensive monitoring system and a multi-level forecasting and analysis method.

Background technique

Geological disaster monitoring is a comprehensive technology that integrates the formation mechanism of geological disasters, monitoring instruments, space-time technology and prediction and forecasting technology. At present, the research and application of monitoring technology methods for geological disasters at home and abroad are mostly carried out around sudden geological disasters such as collapses, landslides, and debris flows.

Monitoring methods are mainly divided into four categories based on the type of parameters for detection. The first is disaster body deformation monitoring, including monitoring methods that mainly measure displacement and deformation information: such as deep underground deformation of disaster bodies, surface deformation and relative displacement monitoring, and surface absolute displacement monitoring. This type of technology is currently relatively mature and has high accuracy. As a conventional technology, it is used for geological disaster monitoring; because it obtains intuitive and direct information, especially the displacement and deformation, it often becomes one of the main basis for forecasting.

The second is to monitor the changes in the physical and chemical fields of the disaster body, such as stress monitoring, geoacoustic monitoring, radioactive element (radon, mercury) measurement, geochemical methods, and geopulsation measurement. At present, it is used internationally to monitor the changes in the concentration of radioactive elements (uranium, radium) decay products (such as radon), chemical elements and their physical fields contained in landslides and other disaster bodies. The physical and chemical fields of geological disaster bodies change, often at the same time The deformation and damage of the disaster body are closely related, and it is ahead of the displacement deformation.

There are also monitoring methods for monitoring groundwater activities, enrichment characteristics, and water quality characteristics of geological disasters. Such as groundwater level (or groundwater pressure) monitoring, pore water pressure monitoring and groundwater quality monitoring. The formation and development of most geological disasters are closely related to the groundwater activities inside or around the disaster body. At the same time, the characteristics of the groundwater itself change accordingly during the formation of the disaster body.

The last is the monitoring of triggering factors, which mainly includes monitoring techniques and methods focusing on monitoring geological disaster triggering factors: meteorological monitoring, groundwater dynamic monitoring, earthquake monitoring, human engineering activity monitoring, etc. Rainfall and groundwater activities are the main inducing factors of geological disasters; the magnitude of rainfall and the characteristics of temporal and spatial distribution are one of the main discriminant indicators for evaluating regional geological disasters (especially the three major geological disasters of collapse, slip and flow); human engineering activities It is one of the main inducing factors of modern geological disasters, so the monitoring of geological disaster inducing factors is an important part of disaster monitoring technology.

There are many single-item or dual-item monitoring instruments in domestic geological disaster monitoring, and their application in forecasting and forecasting is subject to some limitations.

The geological disaster comprehensive monitoring device monitors the main causes of geological disasters. It is not only a complex composed of various monitoring modules, but also an intelligent organic system for analyzing the causes of geological disasters. The monitoring content includes deformation and displacement, physical and chemical fields, inducing factors, groundwater activities, etc. Among them, the deformation displacement adopts non-contact detection, which emphasizes intuitiveness, simplicity and low cost while ensuring accuracy, and introduces high-tech to carry out multi-angle three-dimensional monitoring of disaster bodies, which is the basis of refinement, optimization, progress, new research and development, and prediction Comprehensive project.

Types and monitoring contents of existing geological disaster monitoring instruments

Practice has proved that to accurately predict geological disasters requires simultaneous monitoring of multiple parameters, and it is also necessary to know the parameters and parameters under normal conditions.
