Review article

The article analyzes the possibility of using the analytical method for forecasting the bearing capacity of piles in a bilinear formulation for prefabricated piles. The pile bearing capacity forecasting method in a bilinear formulation is an alternative pile bearing capacity forecasting technique that allows obtaining a load-settlement graph for a single pile, which makes it possible to forecast the pile bearing capacity in an analytical formulation. There were carried out 12 full-scale tests of bored piles and 19 factory-made piles for static indentation load. For each test, there was performed a numerical simulation of pile testing for a static indentation load and an analytical calculation of the bearing capacity of the pile in a bilinear formulation. The results of the analytical calculation are compared with the results of field tests of piles and the results of numerical simulation. Based on a comparison of calculated and experimental data, conclusions have been made about the possibility of using an analytical calculation of the bearing capacity of piles in a bilinear formulation.
