Abstract:
The paper presents discussions of the bearing capacities of precast concrete joint piles
from construction site of the port of Prorva located on the Northeast Caspian Sea. Precast concrete
joint piles with cross-section of 40 cm × 40 cm with the total length of 27.5m were used first time
in the West Kazakhstan. The piles bearing capacities were received by computational methods as
APILE analysis and Kazakhstani standard method, as well as by pile driving analyzer. The analysis
showed that the results obtained by the dynamic method of PDA, APILE analysis and the calculation
method according to the Kazakhstan standard are similar. The methods described in the article can
be applied to determine the bearing capacity of piles and to analyze the interaction of driven piles
with problematic soil ground in West Kazakhstan. Considering the calculations performed, APILE
analysis can be recommended for use in the design and the dynamic PDA method for testing piles
directly on construction field conditions.
