Methodology for formation of anti-landslide engineering protection based on use of risk-oriented approach

Abstract

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.
