The purpose of this work was to substantiate the system of strengthening measures as part of the large-scale renovation of the memorial complex "Victory Square" in Voronezh. The research methodology was based on a route survey of the slope, fixing elements of its structure violation, drilling operations. Results obtained: calculations of the stability of the slope acting as the base of the complex were carried out. By computational and analytical methods using the GEO5 software package, various structures of fortifying structures were modeled and the final version with the taking into account the possibilities of their construction. The device of the following complex of devices is recommended: 1) a series of stabilizing piles along the edge of the slope - drilling, reinforced concrete, diameter 0.4-0.5 m, length 12.0-10.0 m, the upper end of the pile is the surface of the site, the distance between the wells is 1.5-2.0 m, the distance from the edge of the slope is 1.0-1.5 m; 2) the retaining wall at the base of-the spit is 1.0 m deep, the width at the base is 1.5 m, the height (of the part facing the slope) is 3.0 m, the material is concrete. This work can serve as an example of analyzing the condition of slopes stacked with bulk soils, as well as carrying out protective measures on such slopes and modeling anti-landslide structures.

Phosphoric acid production in apatite and phosphate rock processing involves by-production of phosphogypsum which is placed in dumps, landfills and gypsum storage facilities. Phosphogypsym has specific mineral and chemical composition, possesses peculiar physical and mechanical properties, and it is highly susceptible to compaction when piled in dumps. The lab-scale and in-situ deformation testing and monitoring of various phosphogypsum types made it possible to substantiate the deformation behavior model of the rock and to determine its mechanical properties. In view of the complex structure of phosphogypsum storage facilities and considering the deformation specifics of this manmade rock, prediction of phosphogypsum compaction should use 3D FEM-based modeling. Numerical modeling improves reliability of geomechanical behavior prediction in phosphogypsum dumps in terms of the volumetric deformation by taking into account

Today the development of upland quarries with the formation of multi-tiered dumps of overburden rock mass in complex conditions of mountainous terrain and limited land resources still remains a problem. The conducted analysis has shown that the practice of designing of multi-tiered dumps in gorges lacks detailed consideration of the issues determining the stress distribution in the dump body depending on the dihedral angle formed by the slopes of the side faces of the gorge. The point is that the process of overburden dumping is accompanied with the transmission of stress forces to the central axial plane of the dump body formed in the gorge from the side of the gorge inclined surfaces. At the same time, the inclined component of stresses is due to the mass of overburden rocks dumped onto the inclined side surfaces of the gorge. Being directed at an angle to the shear forces acting in the dump, these lateral stresses play a positive role in the acceleration of rock mass consolidation in the clamped environment during the overburden dump formation. The decrease in dump shear forces leads to the increase in dump stability. It also allows to determine the rational volumes of overburden to be laid as well as the main parameters of a multi-tiered dump. It should be noted that there are significant difficulties in identifying and objective assessing the nature of occurrence and distribution of stress forces in the dump being constructed in the gorge using graphic-analytical methods. In the course of the presented study, the author made an attempt to identify and register stress forces in the body of a multi-tiered overburden dump formed in the gorge using physical modeling methods. For this purpose, a three-dimensional model test bench of a multi-tiered dump has been developed. This test bench allows to solve a three-dimensional problem using the method of physical modeling and, identify the stress variation patterns in the central axial plane of the dump model depending on the inclination angles of the side surfaces of the gorge.
