This article discusses the problem of the bearing capacity of piles with defects in the pile body. Field trials were performed using the non-destructive Sonic Logging (CSL) method. The object of the study is bored piles with a diameter of 1.0 ÷ 1.5 m and a length of 8 ÷ 55 m. This article solves the problem of bearing capacity of piles with defects of 10%, 20% and 30%, respectively, in the body of the pile. For modeling, we used load test data from bored piles at the LRT construction site. In this study, only the maximum strain value is needed to compile several cases with various defects using two-dimensional finite element analysis (FEMA) based on the Midas-GTS NX program. According to the results of field tests and modeling of piles, it was found that more than 20% of piles have defects. Field data and numerical simulations have also been confirmed on the recommendation of Bjerrum.
