Dispersive clay soils represent a specific type of fine‐grained soils, which can not be determined by the visual classification or using standard identification ‐ classification tests such as granulometric (particle size) analysis, plasticity tests and similar. The paper gives an overview of the results of testing dispersivity of fine‐grained soil using other classification tests: the crumb test, the double hydrometer test and the pinhole test. Tests were conducted on samples: sandy clay embankment dams of “Rovni”, loess from different locations (Zemun, Novi Beograd, Titel, Kelebija, Srbobran, Slankamen, Ruma, Mali Iđoš) and kaolinite sandy clay deposits Grabež ‐ Aranđelovac. In order to improve soil properties, special consideration was given to the influence of soil compaction to dispersion properties. However, dispersion tests obtained with the use of the pinhole method at different degrees of compaction showed that the degree of compaction has no significant effect on the soil behavior, i.e. its class of dispersion.
The paper presents the static load tests (SLT) and dynamic load tests (DLT) of the piles and numerical analyses of piles in interaction with the soil of wind turbines. Pile tests were conducted using the equipment with counter-weights for SLT and an autonomous system for the control of DLT of the piles. Numerical DLT analyses were performed by the signal matching method. Tests proved that the design resistance of piles of SLT and mobilized static resistance of DLT are higher than the design forces obtained from the design of the wind turbine foundations. Also, the need to develop a plan for testing the bearing capacity of piles, concerning large and significant buildings was emphasized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
