The project consists of a high-rise building supported on boring and driven piles. An assessment was made of the current practice in the foundation design of high-rise buildings in Astana, Kazakhstan, to explore areas for improvement. Pile testing is usually undertaken to provide relevant information on one or more of the following issues: the ultimate load capacity of a single pile, the loadsettlement behavior of a pile, the acceptability of the performance of a pile, and the structural integrity of a pile. A three-stage process of foundation design and verification will be described, and the importance of proper ground characterization and assessment of geotechnical parameters will be emphasized. According to the test results, the bearing capacity of driven and bored piles was determined, and a comparative analysis was carried out according to the results of tests for cone penetration (CPT). The analysis of the obtained results showed that the dynamic DLT method (according to GOST) compared with static SLT (according to GOST) and cone-penetrating tests (CPT, according to GOST) showed a low bearing capacity of about 30-40 percent. According to comparative analyzes, the static testing method of piles was determined to differ from the CPT by about 15 percent. These investigations are important for the understanding of soil-structure interaction, especially of boring and driven piles in construction site Astana. [ABSTRACT FROM AUTHOR] |
