A plurality of rows of wells are drilled in the soil of the area to be
stabilized, and then pairs of electrodes, i.e., an aluminum anode and a
copper-graphite cathode connected to a source of a bipolar pulse current,
are inserted into each well in such a manner that during operation all
anodes of odd wells are connected to a positive terminal (for odd pulses)
of the source, while all cathodes of even wells are connected to a
negative terminal (for odd pulses) of the source. After a certain period
of treatment the anodes and cathodes are reversed so that all anode of
even wells are connected to the positive terminals (for even pulses) of
the source, whereas the cathodes of the odd wells are connected to the
negative terminal of the source. Controlled directional structuring of the
soil mass is carried out by adjusting the duration of current pulses,
intervals between two sequential bipolar pulses of pulse current, and
current density in the pulses. Prior to initiation of the soil
stabilization process, salts, which correspond to the type of treated
soil, are introduced into the wells. Furthermore, water under pressure is
fed to the area of the soil being current stabilized as an additional
measure for affecting soil temperature control.
