Description

A Geological Hazard Monitoring System

technical field

The invention relates to a monitoring system, in particular to a geological disaster monitoring system.

Background technique

The geological disaster network monitoring and early warning system is a kind of real-time measurement, monitoring and on-site alarm for geological disasters in multiple regions designed by using various technical means such as micro-power consumption design technology, wireless communication technology, sensor technology, and high reliability design. , At the same time through a variety of communication methods to network the various regions to achieve a multi-level early warning and alarm monitoring system.

my country's definition of geological disasters is the geological action (phenomenon) that is formed under the action of natural or human factors and causes damage and loss to human life, property, and the environment. 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, etc.

The traditional simple monitoring of geological disasters refers to the monitoring method of monitoring the displacement changes of disaster bodies, houses or structures with the help of simple measuring tools, instruments and measuring methods. Commonly used monitoring methods are as follows: 1) pile method. The buried pile method is suitable for observing the cracks on the collapsed and landslide bodies. On the slope, piles are buried across both sides of the crack, and the distance between the piles is measured with a steel tape to understand the deformation and sliding process of the landslide. For soil cracks, piles should not be too close to the cracks. 2) Buried nail method. A nail is nailed on both sides of the crack in the building, and the deformation and sliding of the landslide can be judged by measuring the distance change between the two nails on both sides. This method is very effective for judging the warning signs of imminent disaster. 3) Paint method. Draw a mark on both sides of the crack of the building with paint, which is the same as the principle of the embedded nail method. By measuring the distance between the marks on both sides, it is judged whether the crack has expanded. 4) SMT method. Paste cement mortar sheets or paper sheets across the cracks in the building. If the mortar sheets or paper sheets are broken, it means that the landslide has undergone obvious deformation, and strict precautions must be taken. Compared with the above three methods, this method cannot obtain specific data, but it can judge the sudden change of landslide very directly.

The monitoring method of group monitoring and group prevention of geological disasters requires regular inspection of monitoring points, and monitoring is carried out every 15 days in the dry season. During the rainy season (April-September), monitor once every 5 days (such as the 5th, 10th, 15th, 20th, 25th, and 30th of each month). In case of weather, especially when the 12-hour rainfall reaches more than 50 mm, the frequency of monitoring should be increased, such as once or more per day, and even special personnel should be arranged to monitor day and night.

Geological disasters occur frequently in my country, and long-term reliance on group monitoring and group prevention has led to the following problems: 1) The causes of disasters are more complex. Special geological environmental conditions such as high mountains and steep slopes, developed fault structures, fragile rock and soil structures, and severe weathering are the basis and root cause of geological disasters. However, with the development of the economy and the acceleration of development and construction, slope cutting, mining, reservoirs Unscientific human engineering activities such as water storage, large-scale extraction of groundwater, and engineering construction have also become the main triggering factors for geological disasters. 2) Disaster early warning points are multi-line long. There are no less than 100,000 geological disaster points in the country. In some areas with complex geological conditions, there may be hundreds of early warning points in a county, and most of these early warning points have inconvenient transportation and communication. The method of group monitoring and group prevention It is very difficult to establish a complete management and supervision organization. It is almost impossible to complete effective monitoring in some monitoring sites with small population. 3) High frequency of disasters. Tens of thousands of geological disasters occur in my country every year, and there were 30,670 in 2010, a significant increase from 10,840 in 2009. An average of more than 80 disasters occur every day. Such a frequency of disasters has brought great pressure to the manual early warning method of group monitoring and group prevention, and also put forward higher requirements for monitoring. 4) The degree of harm is large. With the acceleration of my country's construction and urbanization process, the degree of harm caused by geological disasters is also increasing. At 0:12 on August 8, 2010, the urban area and upstream villages of Zhouqu County, Gansu Province were hit by a huge torrent of mudslides, resulting in 1,501 deaths and 264 missing. Almost all of Yueyuan Village and Chunchang Village were destroyed, Sanyanyu Village and Luojiayu Village were partially destroyed, and thousands of mu of fertile land were buried. After the torrents and mudslides rushed into the urban area of Zhouqu County and the Bailong River, more than 20 buildings were damaged. The river course was silted and filled with a length of about 1 kilometer. Communication lost. Casualties and economic losses were serious. Therefore, the present invention provides a geological disaster monitoring system that can monitor in real time, has high monitoring efficiency, is easy to implement, does not require special personnel to guard, and has low implementation cost.
