Along with other advanced geotechnical technologies for the exploration of underground space, electro-discharge technology (EDT technology) is one of the fundamental in the field of the construction of auger-injection microcircuits, as well as the construction transformation of the properties of foundation soils with weak physical and mechanical characteristics. At the same time, having significant differences compared to other methods of subsurface development of buildings and structures, the geotechnical EDT technology has a number of advantages, such as: 1) increased specific soil load-bearing capacity; 2) constructability of the auger piles in any geotechnical conditions; 3) possibility of geotechnical works performance under restricted conditions. As a basic structure for the development of new technologies, it has a large scientific research potential for the purposes of introducing it into modern underground construction.
