This study is aimed at determining the intermediate strength characteristics of soil at a given depth between boreholes using geoinformation systems. Changes in the strength characteristics of soils under the influence of load are studied, which is important for assessing the bearing capacity of the foundation and developing optimal solutions for its improvement and strengthening. A comparative analysis of Kriging and IDW methods in ArcGIS software package for determining the spatial variation of soil strength characteristics (c, φ) was carried out. The results showed differences in the values of specific cohesion and angle of internal friction varying depending on the chosen interpolation method. The proposed methodology for determining the intermediate soil strength characteristics takes into account the soil overlay, the thickness of the layers and the relative position of the known values obtained from the monolith selection. This is important for accurate determination of the bearing capacity of the foundation.
Key words: specific cohesion / angle of internal friction / spatial interpolation / bearing capacity of the foundation / ArcGIS / IDW / Kriging
