Abstract
The aim of the study is to assess the bearing capacity of driven pile foundations. In order to achieve this goal, piles were accepted as an object of research in site multifunctional complex facility «Diamond» in Astana. The results of field work on the study of the bearing capacity of pile foundations are presented. Field tests are carried out in accordance with the requirements of the construction standard. The bearing capacity of driven piles PT 1-27 immersed in the ground to the abs. mark of the tip of the pile 336.7 m, to a depth of 3-6.3 m, according to the results of their dynamic tests was 615-674 kN. Dynamic tests were carried out in site «Diamond» facility from May to September 2021. The calculated permissible load on the pile, taking into account the reliability coefficient of 1.4, according to the construction standard should be taken equal to 439-481 kN. A large number of the obtained values of bearing capacities ensures reliability and structural strength.
