dc.description.abstract The article presents the results of a comparative analysis of the bearing capacity of bored piles with a drilling displacement system (DDS), obtained by tests for static load and according to GOST standards, as well as the results of tests for compression of the surrounding soil after installing the pile with DDS. These DDS piles are created by rotary drilling with a simultaneous full displacement of the soil in a horizontal direction. The optimal design of DDS piles can be obtained in soils that allow for a horizontal displacement, which causes an increase in the shaft’s resistance. It is shown that drilling and ramming technologies of pile foundation construction play an important role in modern urban planning, but they are not fully universal. Actively developing, they replace traditional methods using dynamic and vibratory impacts, as they are more gentle to nearby buildings, which is most relevant for cities with dense urban development. According to the project design, the field tests of DDS bored piles with a diameter of 410 mm, and length of 6 m was performed by two static loading tests. The static loading tests were performed by GOST 5686-2012. This paper shows the results of the load-settlement and feed rate of the deep auger for pile diagrams 1 and 2 from those field tests that make it possible to determine the bearing capacity of piles on a given soil. The analysis signified that the bearing capacity of the six-meter-high bored piles meets the design requirements. ru
