Abstract
Introduction. This is the first investigation of the behaviour of precast concrete joint piles utilized in challenging soil conditions on a construction site in Kazakhstan. Materials and methods. The following techniques were applied: evaluation of the bearing capacity of SCLT using field test data interpretation techniques and the ASTM’s dynamic DLT method for driving precast concrete joint piles. Results. Only 7 % separated the dynamic DLT-PDA approach from the static approach. This implies that, in comparison to other current methods, the alternative dynamic DLT-PDA method is highly precise and effective. Dynamic tests were conducted by PDA (Pile Dynamic Analyzer) and static tests by the requirements of the American Society for Testing Materials (ASTM). Conclusions. According to the test results have been made design changes in the pile foundation. Static tests (SLT) were carried out on 16-meter piles and precast concrete joint piles with a total length of 25.5 and 27.5 m cross-section 40 × 40 cm. SCLT is a highly accurate and robust system that enables you to monitor static pile tests whilst also ensuring the safety of site operatives. Featuring a cable, users are able to monitor safely and accurately from distance, eliminating the need for personnel to enter potentially dangerous testing zones. This study examined joint piles with a 400 × 400 mm cross section and a pin-joined connection, as well as their relationship with the soil of Western Kazakhstan will be analyzed.
