摘要：It were considered and analyzed the existing schemes of piles work in clay soils.1.Leningrad scientific school,where the formation of pile bearing capacity use as the basis of the thixotropic clay soils hardening and radial soil pressing around the pile shaft during the piles driving with pile-driving equipment for the exploitation period.2.Odessa scientific school,in which the uplift soil formation from the edge pile use as the basis of the pile bearing capacity during the piles driving,the formation of the pressed zones (platform) in the piles edge plane,the gap formation around the pile shaft during its diving by ground pushed moving with the pile edge.3.Preconditions of the pile bearing capacity formation of the pile by the thixotropic soil hardening in time and the radial soil pressing around the pile shaft can not give an answer to the following questions: 1) Why during the pile driving is formed the gap around the trunk of dived piles,when by condition there is a radial soil hardening around the trunk? 2) Why in the interpiled space is formed the lune (deflection),not the soil mass swelling (due to the radial hardening)? 3) By what is formed the calculated soil resistance under the lower end (edge) of the pile? which is about 10 times higher than the calculated soil resistance in the edge plane,according to the Building Code V.2.1-10.2009? The justified answers on all these and other technical and technological matters give perquisites of the Odessa scientific school with additions and authors developments.
