Modern unfavorable physical and geological processes
Karst is a phenomenon associated with the activity of underground water, which is expressed in the leaching of soluble rocks (limestones, dolomites, gypsum) and the formation of cavities (channels, caves) in the rocks, which are often accompanied by sinkholes and subsidence of the roof and the formation of sinkholes. lakes and other depressions on the earth’s surface.
What is Modern unfavorable physical and geological processes?
Modern unfavorable physical and geological processes is the study of soils for the presence of karsts and sinkholes in its layers. Relevant studies are carried out before the construction of various types of structures, the laying of heating lines, highways and tracks and other construction and engineering works, the construction of which depends on the quality and stability of the soil. Karst development stops in the following cases:
- when the modern basis of corrosion increases;
- when the flow of water into karst cavities stops due to the accumulation in them of the residue from the dissolution of rocks (cave clay) and the collapse of rocks (karst breccia), as well as due to the formation of a rather thick layer of eluvium, deluvium and deposits of karst lakes on the surface;
- when the surface of karst rocks is covered by later deposits (fossil or buried karst).
What is a karst hazard?
Karst danger is the threat and possibility of negative impact of karst manifestations on people and karstization of the territory (components of the geological environment, buildings and structures) during their development and exploitation. It is determined, as a rule, by the intensity and parameters of karst deformations,
is assessed (like risk) by possible social, economic and environmental damage.
The karst danger of the territory is assessed on the basis of its comprehensive study using various methods (engineering-geological, geophysical, hydrogeological, geomorphological, etc.), which include qualitative and quantitative characteristics.
Under these conditions, it is important to consider karst danger. Karst danger is the threat and possibility of negative impact of karst manifestations on people and karstization of the territory (components of the geological environment, buildings and structures) during their development and exploitation. It is determined, as a rule, by the intensity and parameters of karst deformations,
is assessed (like risk) by possible social, economic and environmental damage.
Comprehensive studies of soils for karst phenomena
Before carrying out construction or engineering works, it is necessary to carry out complex studies of the territory for the possibility of karst phenomena, landslides, avalanches, as well as dangerous phenomena in the conditions of slopes.
High-precision equipment allows us to simulate the prospects of the geological situation, to determine the risks and potential dangers that threaten the buildings planned on the territory during long-term operation in conditions of unstable soils.
After the works, we give detailed recommendations on measures to strengthen structures to prevent the development of negative consequences.
- Starting with engineering investigations on the research site, we first of all turn to our archive and pick up all the documentation related to previous research over the past 50 years.
- With the help of modern methods and unique equipment, we conduct field tests, including tests with loads on a stamp, static and dynamic sounding, with a pressure gauge, we use the latest geotechnical methods.
Soil and groundwater samples obtained during the tests are examined in our company’s own laboratory.
