Potential risk analysis of geological disasters

Landslide risk hidden danger

Landslide refers to the natural phenomenon that the soil or rock mass on the slope slides down the slope wholly or dispersedly along the weak surface or weak zone under the influence of river scouring, groundwater activity, earthquake and artificial slope cutting. It is often called mountaineering, mountain collapse, ground sliding and soil sliding.

The occurrence of landslide is mainly related to geological factors and climate factors. Landslides are easy to occur in areas such as river bank slope, engineering building slope area, geological structure zone, mudstone and other geotechnical distribution areas, rainstorm-prone areas or abnormal heavy rainfall areas.

To reduce the risk of landslide, the prevention and control of landslide should start from the following two aspects. The first is to eliminate and reduce the harm of water. Groundwater is discharged through horizontal drilling, vertical drilling and shaft pumping. To prevent the softening, dissolution and decomposition of rock and soil, and reduce water erosion and wave impact.

After graduation, students majoring in geology can go to petroleum, coal, minerals, energy and other industries to engage in geological exploration, geological research and other related work, or they can go to government departments, colleges and research institutes to engage in civil servants, teachers, researchers and other occupations.

The main work of geological engineers and technicians is geological exploration, engineering technology and geological investigation. Geological exploration is an investigation and research activity to carry out non-geological exploration and detection through various means and methods, determine the appropriate bearing stratum, determine the foundation type, and calculate the foundation parameters according to the bearing capacity of the bearing stratum. It refers to the discovery of industrial deposits in mineral survey and the investigation and study of geological conditions such as rocks, strata, minerals, hydrology and landforms in a certain area.

What does the geology major do outside?

Geology is a science major, which requires students to master the basic knowledge of natural science, basic theory and basic knowledge of geology. Receive systematic training in basic skills of geological work, geological scientific research and computer application, and foreign language exchange. And cultivate basic research ability and strong practical skills, so that students can engage in geological science research or teaching in scientific research institutions and universities, and engage in technology development and technology management in marine, petroleum, geology and minerals, jewelry, materials, environment, basic engineering, tourism development and other departments.

Students majoring in geology usually need to study GIS principles, introduction to geology, hydrogeology, remote sensing and GIS, sequence stratigraphy, geophysical exploration, general petrology, sediment analysis, geotectonics, stratigraphy, sedimentology, geomorphology, physical geography and other courses.

3. The influence of landform on tourism resources

(1) Landscape tourism resources, such as mountain landscape, karst landscape, Danxia landscape, sandstone peak forest landscape, sandstorm landscape, volcano landscape, glacier landscape, coastal landscape, etc.

(2) Water landscape tourism resources, including oceans, rivers, lakes, waterfalls, coasts and various springs.

(3) Biological landscape tourism resources, including forests, grasslands, all kinds of wild animals and marine life.

(4) Natural zonal landscape tourism resources, such as tropical landscape.

(5) Climate tourism resources, such as Xia Han Resort and temperate and subtropical resorts with pleasant seasons.

(6) Weather and meteorological tourism resources, featuring astronomical landscapes, such as the sunrise on Mount Tai, the cloud waterfall on Mount Lushan, the sea of clouds on Mount Huangshan, the S-ray of Emei Giant Buddha, a mirage in the desert, polar aurora, etc. It's rare, but it happens frequently.

(7) Other natural tourism resources, such as special natural phenomena. Among the numerous natural scenery tourism resources, beautiful scenery, rugged rocks, waterfalls of springs, sunny beaches, pleasant climate, rare birds and animals, and beautiful flowers and plants combine to form famous scenic spots with different styles, which often become tourist attractions for people to visit, summer vacation, recuperate and various sports activities.

On the night of June 28th, 20 18, official website, Jiuzhaigou Scenic Area issued a notice: Recently, there was continuous heavy rainfall in Jiuzhaigou County, and on the night of June 25th, serious mountain torrents and mudslides broke out in Jiuzhaigou Scenic Area. According to the forecast of the meteorological department, the rainy weather will continue, the meteorological department will issue a four-level meteorological risk warning, and the land department will issue a two-level geological disaster risk warning, which means that the safety risk of the scenic spot is high.

: 20 10-20 10, engaged in the work of geological disaster prevention technicians after graduation. I can evaluate assistant engineer for 2 years, engineer for 6 years, and senior engineer for 12 years. With rich professional and technical work experience, he can also serve as the technical or management personnel such as the person in charge of geological disaster investigation projects, the person in charge of subordinate departments of geological units, the person in charge of geological units or the chief engineer. When I entered the Department of Land Management and Geological Environment Monitoring, I could be a staff member of Township Land Institute, Geological Environment Department of County Land and Resources Bureau, Geological Environment Monitoring Station, Provincial Land and Resources Bureau and Geological Environment Monitoring Station at first. Graduates can engage in the investigation, evaluation, monitoring and forecasting of geological disasters in enterprises and institutions such as geology and mineral resources, nonferrous metals, transportation, urban construction, environment, earthquake, mines and land and resources management.

4. Geological disasters in scenic spots

Plain: Suitable for planting, with little influence and restriction on agricultural production and large production scale.

Hilly: It has a certain slope and can be transformed into terraced fields as needed, but it is easy to cause soil erosion. They are suitable for planting fruit trees and tea, and are also suitable for grazing.

Mountainous area: the terrain is undulating, which restricts agriculture greatly. Generally, only animal husbandry and forestry can be developed.

Plateau: the plateau is wide, which can develop animal husbandry and planting.

Basin: Good hydrothermal conditions can develop fruit cultivation. If the terrain inside the basin is flat, such as Chengdu Plain in Sichuan Basin of China, planting can be developed.

The original ground is the original ground elevation of the ground before construction. The original ground survey is mainly for volume measurement and settlement in the later stage of the project. Through the relationship between the original ground and the ground to be built, the cross section can be drawn or the volume to be filled or excavated can be calculated. It can also be used to check the volume or elevation given by the design institute. Therefore, preliminary ground investigation is very important to the overall nature of a project. I hope the answer will help you.
