Analysis of the stability of the landslide slope in Sochi

Abstract

The article presents a methodology for assessing the stability of a landslide slope, an inhomogeneous geological structure, taking into account the planned load and seismic impacts. When considering the calculation of the real object of the landslide slope in Sochi, the main attention is paid to the analysis of the results obtained with respect to their reliability. Landslide slopes are particularly complex both in their geological structure and in relation to the loads and natural factors acting on them. To analyze the behavior of such complex geotechnical objects, a number of software packages based on the finite element method are currently being proposed.

Within the framework of these complexes, it is possible to take into account a wide variety of initial and boundary conditions. However, with regard to the elastic-plastic work of soil massifs, there are certain difficulties associated precisely with the assessment of the limit state. Therefore, in practice, limit equilibrium methods are used for this purpose.

The scientific and regulatory literature on geotechnics provides a large number of different methods for assessing the stability of slopes. At the same time, the approach to calculating the stability of soil massifs based on linear programming and implemented by the simplex method can be recognized as the most reasonable. Here, within the framework of the calculation scheme of the compartment methods, static equilibrium equations are performed without involving additional hypotheses, which significantly increases the reliability of the results. This direction has not yet become widespread in the practice of designing slopes and slopes. To a certain extent, this is due to the fact that linear programming methods have not yet found mass application in continuum mechanics. Although some progress is being observed here.

Therefore, the development of specific algorithms for calculating stability by the simplex method, in particular landslide slopes, seems to be an urgent task, to which this article is devoted.
