Abstract:
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.
