USE OF GIS TECHNOLOGIES FOR ZONING URBAN AREAS TAKING INTO ACCOUNT ENGINEERING-GEOLOGICAL CONDITIONS

Abstract

To solve the problem of insufficient accounting of engineering-geological conditions and types of soils in the territory of the Republic of Kazakhstan, it is necessary to systematize and generalize information on engineering-geological conditions. This goal can be accomplished through the utilization of contemporary geoinformation systems (GIS), which enable the integration and examination of extensive datasets encompassing findings from drilling engineering-geological boreholes. The creation of a geoinformation database based on a dataset including a map of the city with specified X, Y, and H coordinates, as well as the results of drilling more than 500 engineering-geological boreholes studied from 2014 to 2022 in one of the main industrial cities of Kazakhstan, Pavlodar city, is an example of this approach. By analyzing the obtained data, the zoning of the territory with regard to engineering-geological conditions and soil types was carried out, five main engineering-geological elements (EGE) were identified, the physical-mechanical properties of soils were assessed, and engineering-geological maps of quaternary deposits and bedrock were created, as well as special geotechnical maps, including a map of groundwater level, which will help improve the quality of design and construction of buildings and structures in the city and in the whole territory of the Republic of Kazakhstan. Also, an analysis of the interaction of the soil base and strip foundations was carried out, and based on the results obtained, the optimization of design solutions through their typing, depending on the choice of geometric dimensions of the strip foundation base, was proposed.
