Abstract

This study evaluates the load-bearing capacity of pile foundations, with a focus on those used in the “Multifunctional complex”. The objective of the field tests was to determine the bearing capacity of two driven piles, Nos. TR7 and TR18, type C9.30, installed to depths ranging from 4.1 m to 3.5 m, with final shaft elevations of 340.51–341.34. In addition, one driven pile No. TR34, type C11.30, was installed to a depth of 3.6 m. Two test piles of grade C9.30 (TR7 and TR18) and one test pile of type C11.30 (TR34) were subjected to load testing. Driving operations were performed on July, 2021, using a Juntan PM-25 pile-driving rig equipped with an NNK-5A hydraulic hammer weighing 5000 kg. Field load testing was conducted after a pile “rest” period of 28 days following installation. The load-bearing capacity of the pile according to the results of static load tests on the above-mentioned site of construction amounted to 799 kN.
