The purpose of this work is to develop a methodology for the formation of anti-landslide engineering protection based on the application of a risk-based approach. The devel-opment of these methodological approaches is being tested on the territory of the Voronezh re-gion. Research methodology. Consideration of this problem for the territory of the Voronezh region was made on the basis of the methodology of the risk-based approach. An algorithm for implementing the methodology is presented. Areas that differ in the level of landslide hazard are identified. Detailed studies of the geological and hydrogeological structure of the territory of the Voronezh region were carried out to identify risk-oriented factors. The results obtained: The algorithm for implementing the methodology for anti-landslide protection of a specific ob-ject includes the sequential execution of the following steps: identification of landslides; pre-diction of the risk of soil movements and landslides; determination of the structure of possible damage from a landslide, determination of the laws or dependencies of the distribution of dam-age from a landslide, establishment of quantitative characteristics of the measure of the risk of landslides, the stage of determining effective preventive measures that affect the reduction of the risk of landslides, and evaluating their effectiveness. Based on the application of the methodology of the risk-based approach, an effective system of anti-landslide protection has been built, taking into account a set of security-restrictive, engi-neering and technical and special active and passive measures.

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.
