The authors provide an overview of multiple cases of application of piles, made through the use of electric discharges, as the foundations of high-rise buildings. The values of the bearing capacity of RIT piles identified on the basis of static field tests of specific construction facilities are provided. Nine RIT pile buildings, the height of which varied from 90 to 140 meters, were built before 2012.
The total number of high-rise buildings that rest on RIT piles is equal to nine. They are made of fine concrete prepared according to State Standard 26633-91*, B30 class of compression strength, and W10 grade of water permeability. The reinforcement of RIT piles was performed through the application of the reinforcing cage composed of two sections. A500C steel was used for longitudinal (bearing) rods, the design compressive strength was equal to 435 MPa; dimensions of the bearing steel were based on the principle of perception of the whole design load. The concrete transmitted the load into the soil and protected the steel from corrosion.
On the basis of the analysis of the monitoring results, the technology and tests of PIT piles, a conclusion can be made that PIT piles, that have a diameter of 320 mm, assure the pre-set reliability of high-rise buildings in complex engineering and geological environments.
