Sažetak
A great deal of data which determine the characteristics of engineering soils was collected in the course of geotechnical explorations conducted for the purpose of building two industrial objects near Kutina (Tvornica umjetnih gnojiva / Artificial fertilizer factory II and Soot Factory II/ Čađara II).
Wishing to familiarize ourselves with the condition of homogeneity/heterogeneity underneath the object, we decided to check the hypothesis regarding the homogeneity of the a priori acquired geotechnical mediums and their geotechnical similarity. The relationship of the two mediums under observation is superpositional, they are lithologically similar but genetically different. They are represented through an engineering geological model reaching the depth of forty meters.
Following the basic statistical data analysis for identification, geotechnical parameters and the use of several statistical tests, we were able to reach an engineering judgment on the basis of statistical conclusions. We realized that, from a statistical point of view, both geotechnical mediums are mostly homogenous or, speaking from the engineering point of view, ''quasi-homogenous''. The comparison of these two mediums showed that there is no statistically significant difference according to certain geotechnical parameters of geotechnical parameters. It follows, therefore, that the unification of the superpositioned mediums in a physically united halfspace located under the object is acceptable.
