In the case of insufficient relevant data for the individual soil layer, these can be estimated using the appropriate correlations. The results of the previous research indicate a significant dependence between the granulometric composition of the soil, the Atterberg limits of liquid and plasticity, and the shear strength and deformability in the fine grained soils. From more than 50 locations in the Republic of Croatia, undisturbed soil samples were taken, with 230 laboratory tests performed. A total amount of ca. 1100 relevant data were obtained The mentioned data were analyzed by the implementation of standard statistical methods, in order to represent the correlations between the measured values of individual geotechnical parameters. The paper presents the results of the mentioned analyses and compares the obtained results with correlation relations of vari...

Its selection has to be based on technical principles and standards of engineering practice. It has been shown that the results of engineering assessment of different authors for the same problem and input data are significantly dispersed. A survey was conducted in which participants had to estimate the force that causes a 10 cm displacement at the top of an axially in-situ compressed pile. 50 experts from all over the world took part in it. The lowest estimated force value was 42% and the highest was 135% of measured force resulting from a mentioned static pile load test. These extreme values result in significantly different technical solutions to the same engineering task. In case of selecting a characteristic value of a geotechnical parameter the importance of the influence of an engineering assessment can be reduced by using statistical methods. An informative annex of Eu...

The isolation of the landfill must protect groundwater from dangerous and harmful toxic components in the effluent, particularly those containing chromium. The isolation layer is most commonly made up of low permeable of impermeable clays. In this paper we analyze a sample of clay from a clay deposit near Varaždin in order to determine its suitability as isolation material.
