How to prevent landslides

How to prevent landslides, landslides are a common natural disaster, but the harm to people is very great, every year there are people who lose their lives because of natural disasters, so the face of natural disasters we should be more active to prevent. How to prevent landslides? Below is the information I have organized for you for your reference.

How to prevent landslides1

1, the establishment of geologic disaster monitoring and early warning system engineering

The establishment of professionals and group monitoring and prevention of a combination of monitoring teams, the important . Geological disaster points to establish a professional team-based monitoring network points, the establishment of other geologic disaster points of group monitoring and group prevention of the main, and with the professional team guidance and regular inspections of the combination of monitoring network points, through the professional monitoring system, group monitoring and group prevention of monitoring systems, information systems to achieve the mountainous areas of geologic hazards of the timely monitoring, for the government and the relevant departments of the prevention and control of geologic hazards, the protection of people's lives and properties, disaster prevention and mitigation of decision-making and implementation of a scientific basis and technical support. The system provides a scientific basis and technical support for the decision-making and implementation of disaster prevention and mitigation.

2, the establishment of mountain geological hazards expert analysis system

After a landslide occurs, the local government geologic disaster prevention and control work command convened by geologic disaster and related experts to convene a meeting, analyze the monitoring and early warning system to collect information, determine the state of the landslide body and the level of early warning, estimation of the scope of influence of the surge to form The first step in the process is to make sure that you have a good understanding of the situation, and that you have a good idea of what you are doing.

3. Determine the release of early warning information, standardize the release of early warning information

The Chinese People's **** and State Emergency Response Law stipulates that: can be early warning of natural disasters, accidents and disasters or public **** health events are about to occur or the possibility of occurrence increases, the local people's governments at or above the county level should, in accordance with relevant laws, administrative regulations and regulations, and the local people's government. shall, in accordance with the relevant laws, administrative regulations and the authority and procedures stipulated by the State Council, issue a corresponding level of warning, decide and announce that the area concerned has entered the warning period, and at the same time report to the people's government of the next higher level, which can be reported at a higher level if necessary, and inform the local garrison and the people's government of the adjoining or related areas that may be jeopardized. Thus, the early warning information should be clearly issued by the local government in a formal form, and the departments take corresponding measures according to the warning level issued by the local government.

4, the establishment of a linkage mechanism

Landslide disaster prevention and relief work, involving monitoring, early warning, disposal, disaster relief and other aspects of the need for each unit, each department has its own role to play, and closely cooperate, only in the local government under the unified leadership of the overall linkage of the relevant units, take the initiative to act, actively respond to, in order to maximize Avoid or reduce the loss caused by landslides.

What are the hazards of landslides

The most important hazards of landslides in the countryside are the destruction of farmland, houses, injury to people and animals, the destruction of forests, roads, and agricultural machinery and facilities and water conservancy and electricity, etc., and sometimes even cause devastating disasters to the countryside.

Landslides in cities and towns often bury houses, casualties, livestock, destruction of fields, destruction of factories, schools, institutions, etc., and the destruction of various facilities, resulting in power outages, water outages, shutdowns, and sometimes even the destruction of the entire city.

What are the precursors of landslides

1, before the big slide. In the foot of the leading edge of the landslide, there are blocked for many years of the spring resurrection phenomenon, or the spring suddenly dried up, the water level of the well suddenly changed and other similar anomalies.

2, in the body of the landslide. Horizontal and longitudinal radial cracks appear in the front, it reflects the landslide body pushed forward and impeded, has entered the state of pro-slip.

3, before the big slide. The foot of the leading edge of the landslide body, the soil body appeared on the phenomenon, which is the landslide obvious forward pushing phenomenon. There is rock cracking or shear extrusion sound. This phenomenon reflects the deep deformation and rupture. Animals are very sensitive to this, there are abnormal reflections.

4, before the slide. Landslides will be surrounded by small collapse and relaxation of the rock body. If there is long-term displacement observation data in the landslide body, then before the big slide, whether horizontal displacement or vertical displacement, there will be an accelerated trend of change. This is a clear sign of a near-slide. The cracks at the trailing edge of the landslide expand dramatically, and hot air or cold air emerges from the cracks. Before the landslide, the animals within the landslide body are alarmed and abnormal, and the plants are perverted. For example, pigs, dogs and cows are frightened and do not sleep, and rats scurry about and do not enter their holes. Trees withered or crooked, etc.
