Conclusions
1. Based on a probabilistic approach taking into account the natural heterogeneity of the soils in the engineering-geologic elements and the depths at which they are located, the analytical value of the pile bearing capacity was obtained (for the specified probability of unfailing operation) from the static penetration test results.
2. The analysis of the factual material indicates a possible increase, by 16–25% (for R=0.95) in comparison with the SNiP II-17-77 Norms (since January 1, 1987 with the SNiP 2.02.03-85 Norms) of particular values of the limit resistance of the pile at the penetration point.
