In addition to the numerical simulation results of field tests conducted in accordance with the requirements of national standards, the dependence of the load-precipitate and results of field and numerical experiments are compared.
The results of the tests proposed an analytical model to calculate the bearing capacity of the concrete screw piles. A distinctive feature is that, instead of the coefficient of friction on the lateral surface criterion, the following soil strength criterion - Mohr-Coulomb – is applied to the pile interaction with the surrounding soil. This fact allows a more reliable calculation of the screw pile bearing capacity. To calculate it, one only needs the test results of soil samples in the cut.
