A UNIVERSAL METHOD FOR ASSESSING THE BEARING CAPACITY OF THE BASE OF A PRESSED PILE BASED ON THE SOLUTION A PARTICULAR PROBLEM OF SOIL MECHANICS ABOUT ITS STABILITY AND THE USE OF PHYSICAL AND MECHANICAL PROPERTIES OF SOILS

Abstract

The article presents a universal method for assessing the ultimate resistance of base foundations to the pressing of piles of all types (ready-made, stuffed), according to the classification of TKP 45-5.01-254-2012, according to the physical and mechanical characteristics of soils, taking into account their design parameters, technological aspects of manufacture and device. The method is developed on the basis of the proposed analytical solution of a particular problem of the theory of the ultimate equilibrium of soils in relation to the stability and bearing capacity of the base of a single pile loaded with vertical indentation/pulling force in a flat formulation. The calculation of the characteristic (bearing capacity) and design limit resistance of the foundation to the pressing of piles is carried out using partial coefficients that take into account the possibility of deviations of the structural, technological parameters of piles, soil properties from their representative values and the uncertainty of the soil model compared with the actual behavior of the loaded soil. The deviation of the calculation results according to the proposed method from the experimental data on the results of testing piles with a static indentation load is within the error of the test method.
