Seismic microzoning of the Bendery territory
Relevance of the work. Destructive earthquakes on the territory of Moldova were often accompanied by the death of people and caused substantial material damage, which indicates the need to take measures to ensure the seismic safety of the population and reduce economic damage. Seismic microzoning of the city of Bendery is an assessment of seismic hazard, which takes into account the influence of local engineering and geological conditions on the intensity of seismic vibrations on the Earth's surface, and determines the corrections that reduce or increase the seismicity of the city territory, specified by maps of general seismic zoning. Purpose of the work - clarification of the initial scoring of the territory, to study its engineering and geological conditions. The methodology of the research. Seismic microzoning of the territory of Bendery was carried out in 4 stages: clarification of the initial ballisticness of the territory; study of engineering and geological conditions of the territory; analysis of the expected response of the site to assess the characteristics of an earthquake on the day surface and interpretation of the results of microzoning; drawing up a map of seismic microzoning of the territory. An analysis of the expected site response was carried out to assess the characteristics of an earthquake on the day surface and the results of microzoning were interpreted. Research results. A non-watered or slightly watered aeolian-eluvial-deluvial stratum was taken as a reference soil. Maps of seismic microzoning of the territory of Bendery were compiled. Updating the map of seismic microzoning in Bendery increases the efficiency of anti-seismic measures in design and construction, is an important tool for urban development, understanding the degree of seismic risk and the nature of damage caused by possible strong earthquakes. Conclusions. The map-scheme of seismic microzoning of the territory of Bendery developed by the authors can be used for the design and construction of facilities.
