Engineering geophysical surveys

Geophysical surveys, as a separate type of research, are a complex set of engineering works aimed directly at solving the most non-standard tasks in the field of engineering-geological and related surveys. Often, this type of research is carried out in conjunction with geological, hydrogeological and archaeological surveys.
The need for engineering geophysical research arises in the case of the specificity of the tasks being solved and the non-traditional conditions for the work. The fact is that geological conditions are a very variable structure, and its detailed study will be very costly, and sometimes impossible. In this case, geophysical surveys are carried out.

Geophysical surveys – main goals and objectives

Geophysics in practical application is a relatively young science, but even now it allows solving complex problems. And with a competent formulation of questions and the right choice of methods of geophysical surveys, its main goal will be achieved.
The main goal of geophysical surveys is a significant reduction in the cost of the main complex of surveys and the maximum increase in its information content.

Geophysical research solves a number of problems:

  • Detailed study of the geological conditions of the territory in order to identify voids in the rocks and their geophysical characteristics;
  • Study of the hydrogeological component of the territory, the conditions for the occurrence of aquifers, water properties, the degree of soil moisture, etc;
  • Analysis and study of the processes and phenomena of the geological environment – landslide processes, karsts, suffusion phenomena;
  • Observations of soil masses located in the zone of active development, and later in the process of building operation;
  • Identification of a network of underground utilities and structures;
  • Examination of concrete and reinforced concrete structures in order to search for deformations and identify weakened zones;
  • Determination of the thickness of technogenic bulk soils on the sections of the passage of highways;
  • Determination of the cultural layer in the justification of archaeological work.

The composition of geophysical surveys

As a set of works, geophysical surveys are a complex type of research that requires certain production capacities and resources. They are carried out to survey and monitor large industrial facilities, residential buildings, roads and railways, hydraulic structures, as well as in the study of archaeological research objects.

Geophysical surveys include:

 

  • Seismic exploration;
  • Electrical exploration work;
  • GPR works;
  • Geophysical exploration of wells.
