Abstract

Despite the fact that the Mohr-Coulomb theory of strength appeared more than a hundred years ago, many authors are still conducting research in accordance with the recommendations to find optimal solutions to practical problems. From the Coulomb-Mohr theory, a huge number of methods for solving applied problems were formed, for example, the initial critical load, which is useful for research in the article. This formula is no longer new, but despite this, it is still the object of research. The authors of this article consider the case of the assumption, applying it when issuing a formula for the initial critical load. Based on the initial critical load, a formula for the design soil resistance was obtained, which is still regulated by codes and standards in the field of design. The authors reflect the main ependencies that appear in the calculation of the stress-strain state in soil mechanics. Based on these dependencies, the amount of allowable stress is revealed, under which the condition of linear deformability will be satisfied. The authors have shown that the proposed formula for any stability parameters will correspond to the Mohr-Coulomb limit state condition. The conclusion of the article compares the effect of the formula obtained by the authors and the recipe of the formula obtained by N.P. Puzyrevsky.
