Geophysical and geochemical surveys are important steps in the geological survey process, helping to collect detailed information about the physical and chemical properties of soil and rock in the project area. This process helps evaluate geological factors affecting the project, thereby providing appropriate technical solutions and ensuring construction safety.

Geophysical surveying is the use of specialized methods and equipment to measure and record the physical properties of rocks, such as electrical conductivity, magnetism, and seismic waves. Commonly used geophysical methods include resistivity measurements, magnetometry, and seismic surveys. This helps determine the structural characteristics of the ground, the depth of the soil layers, and the presence of potential factors such as underground sinkholes, geological faults, and weak soil layers.

For example, resistivity measurement is used to determine the electrical conductivity of soil and rock, thereby evaluating the moisture and water permeability of the ground. Magnetometry helps determine the presence of magnetic minerals, providing information about the structure and composition of rocks. Seismic surveys use seismic waves to evaluate the depth and mechanical properties of soil layers, helping to identify potential factors such as underground sinkholes and weak soil layers.

Geochemical survey is the collection and analysis of soil and rock samples to determine their chemical characteristics. This process includes taking soil and rock samples from survey locations, then conducting chemical analysis in the laboratory to determine chemical components and pollution factors. Geochemical surveys help evaluate the pH, mineral content, and presence of pollutants in soil and rock, thereby providing technical solutions to improve soil quality and protect the environment.

Geophysical and geochemical surveys not only help evaluate the physical and chemical properties of soil and rock but also provide important information for designing foundations and construction works. For example, the results of geophysical and geochemical surveys help determine the depth and characteristics of soil layers, thereby designing appropriate and effective foundation solutions. In addition, understanding the chemical properties of soil and rock also helps propose measures to improve soil quality and minimize negative impacts on the environment.

Finally, geophysical and geochemical surveys also play an important role in project planning and management. Having complete information about the physical and chemical properties of soil and rock helps project managers make correct and effective decisions, thereby planning reasonable construction and optimizing resources. and time, minimizing costs incurred due to design changes or troubleshooting.

In summary, geophysical and geochemical surveys are important steps in the geological survey process, helping to collect and analyze detailed information about the physical and chemical properties of soil and rock in the project area. judgment. Carrying out complete and accurate geophysical and geochemical surveys not only helps evaluate geological factors affecting the project but also provides appropriate technical solutions, ensuring safety and stability. for construction works.
