Abstract:
In this paper, joint precast piles with a cross-section of 400 × 400 mm and a pin-joined
connection were considered, and their interaction with the soil of Western Kazakhstan has been
analyzed. The following methods were used: assessment of the bearing capacity using the static
compression load test (SCLT by ASTM) method, interpretation of the field test data, and the dynamic
loading test (DLT) method for driving precast concrete joint piles, including Pile Driving Analyzer (PDA
by ASTM) and Control and Provisioning of Wireless Access Points (CAPWAP) methods. According to
the results, the composite piles tested by the PDA (by ASTM) method differ by 15 percent compared
to the static load method, while the difference between the dynamic DLT (by ASTM) method and the
static load (by ASTM) method was only 7 percent. So, according to the results, the alternative dynamic
method DLT (by ASTM) is very effective and more accurate compared to other existing methods.
