Experience of using precast concrete joint piles in the construction of a Cargo offloading facility in West Kazakhstan

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.
