Abstract
This study examines the application of interpolation technique using ArcGIS software to determine the average mechanical properties of soils in a specific area. The study of soil geotechnical properties plays an important role in construction design and reliability. However, constraints such as limited resources and difficulty in accessing test sites can make it difficult to conduct laboratory and field work on each soil sample. Therefore, the use of interpolation techniques can fill data gaps and provide a more comprehensive understanding of the soil layer characteristics. The proposed Kriging interpolation methodology allows setting the required depth and obtaining accurate values of geotechnical soil characteristics, which facilitates the assessment of engineering and geological conditions at the construction site. This can reduce the cost of survey work and provide data not only for idealized conditions, but also for realistic ground layering scenarios. The proposed methodology also serves as a practical tool for foundation base visualization, providing engineers with a complete understanding of the mechanical characteristics of the soil and helping to select optimal foundation types and sizes.
