Estimation of bearing capacity and settlement plays an essential role in designing pile foundations
of buildings. This paper presents the results of pile static and dynamic loading tests taken place in the
construction sites of Caspian Sea Port Prorva and Tengiz. The static loading tests (SLT) and static compression
loading tests (SCLT) were carried out according to the Kazakhstan GOST and ASTM standards correspondingly.
The dynamic loading tests (DLT) were performed by GOST, as well as by pile dynamic analyzer (PDA) in
accordance with ASTM standards. According to the results of DLT of driven joint piles (with a cross-section of
40×40 cm, lengths of 25 m and 27 m) performed by PDA, the bearing capacity of the piles was 2143 kN. In the
construction site of Prorva, the bearing capacities of driven joint piles according to the results of SCLT were
2067 kN and 2042 kN. In the construction site of Tengiz, the bearing capacities of driven piles tested by SLT
were 1000 kN and 1605kN. These investigations are important for the understanding of soil-structure interaction,
especially of driven piles with a cross-section of 40x40 cm and lengths of 12 and 16m in construction site Tengiz.
