“…Secondly, the main distinguishing feature of this work from the previous studies [10,11,24,25,29,31] is the creation of a geotechnical map that was built for the driven piles. According to the geological structure of the foundations, the optimal variations in the pile length for each city zone were determined.…”

“…In order to determine the above reasons and soil characteristics, it is often necessary to conduct additional soil examinations, which in general will lead to an increase in the cost of construction and exploration work [27]. In this case, it became necessary to create a geotechnical base for the city of Nur-Sultan, which allows digitalizing the existing data of engineering and geological surveys to this day and is able to preliminarily determine the vertical profiles of soil layers using existing boreholes data [28,29]; thus, contribute to a more accurate determination of the pile length and its sufficient bearing capacity.…”

Development of a geotechnical database for the young capital of Kazakhstan, Nur-Sultan city, became a paramount concern of both the scientific community and industry. The creation of the Kazakhstan model of the geotechnical database was based on a fixed dataset which included a city map with determined X, Y, and H coordinates and the user generated data obtained from the materials of engineering and geological surveys from more than 2000 boreholes. Based on the assessment of the built-up area of the city, six main engineering-geological elements (EGE) were identified. The territory of the city was regrouped into eight zones instead of the previous six based on the geological origin and stratigraphy interposition of the EGE. Engineering properties of the soils were considered for physical and mechanical characteristics, where the plasticity limits demonstrated an accurate correlation to the elasticity modulus E and distribution boundaries between the alluvial and eluvial types of the soil on the graph. So, the increased liquid and plastic limits are replicated by higher values of elasticity modulus E, and hence better strength characteristics of a particular soil layer and vice versa, while the moisture content and soil density did not show any obvious pattern and requires additional verification on the construction site. Finally, a geotechnical map was built for the driven piles and the optimal variations in the pile length for each zone were determined.

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.
