near-surface geophysics

The aim of the work: conducting geophysical electrical exploration using vertical electric sounding (VES) in ERT modification to analyze the electrical resistivity of soil and subsoil and identify the areas of karst formation in the plan and to a depth of 100 m during the design and construction of the Moscow – Saint Petersburg Highway. All work was carried out according to the Code of Practice 11-105-97 (parts 1, 2, 6).
