AbstractAbout AuthorsReferences
The problem of increasing the bearing capacity of the base is an urgent problem in modern geotechnical construction. At significant external loads transferred to the base, the use of traditional technologies is not always justified. Often there is a need to use non-standard methods of strengthening the bases. In many cases, the geotechnical situation is aggravated by the presence of weak underlying layers with unstable physical and mechanical characteristics in engineering-geological sections. When strengthening such bases with the help of traditional piles, the latter can get negative friction, which significantly reduces their bearing capacity on the ground, sometimes reaching zero values. This can lead to additional precipitation of the objects being built and erected in the zone of geotechnical influence. The use of electric discharge technology to strengthen the bases with piles in most cases successfully solves many complex geotechnical problems.
