Research of the Stability of the Ground Slope

Abstract

AbstractThe article analyzes the engineering and geological conditions of a landslide slope located in the city of Nizhny Novgorod, which is in a state of dynamic equilibrium. In connection with the proposed development of this site, the question arises of maintaining its stability after the construction of new facilities, taking into account the occurrence of additional load on the slope and possible changes in hydrogeological conditions. To solve this question, the article identifies possible risks, considers the main models of the behavior of the soil base, taking into account negative factors and increasing load, calculates the stability of soil arrays using various well-known methods using engineering and finite element software systems. The geometric scheme of the computational model was built on transverse profiles. The width of the calculated area was chosen in such a way that there were no changes in the stress-strain state of the array due to the introduction of artificial boundary conditions at the edges of the finite element grid. Various methods of landslide protection of this slope are considered, taking into account the existing local construction base. Based on the calculations made, a variant design of methods for strengthening the slope was carried out and the most effective option was selected, providing reliable fastening and minimal impact on the existing slope.KeywordsLandslide slopeStatic stabilityDrill-injection pilesLandslide pressureGeological structure
