Opis (srp)

The chemical soil stabilization technique, whose effects are of a permanent nature, has been successfully applied exclusively in surface layers. On the other hand, the electrokinetic soil treatment, owing to the action of direct current, can be used at greater depths, but the effects of its application are not permanent. The combination of these two techniques aims to develop a soil stabilization methodology that allows for permanent improvement of soil geomechanical properties at greater depths and in conditions where conventional stabilization techniques provide limited results. Within the framework of the dissertation, the efficiency of ten different stabilizers was first examined using the chemical stabilization technique, as well as the change in the mineralogical composition of clayey soils under the influence of a low-voltage electric field. The stabilizers used were classified into three categories: traditional, alternative and stabilizers based on industrial waste. From each of the aforementioned groups, the stabilizer that achieved the best results was selected and in the next stage of the research, clayey soil was treated with it in combination with the electrokinetic treatment. During the second stage of the research, extensive laboratory tests of the physical and mechanical properties of the soil were carried out before and after the soil treatment with the proposed technique, as well as monitoring the rate and amount of cation transfer. In the last stage, a series of studies were conducted on experimental models using the most effective stabilizer from the previous stage of the research in combination with the electrokinetic treatment, examining the effects of different soil moisture contents, electrical voltages and electrode spacing (distance between anode and cathode), with the aim of optimizing the proposed technique for future research on field models. During the whole experimental program, all treated soil samples were tested at different time intervals during and after the treatment, in order to observe the durability of the effects of improving soil properties. The results obtained indicate significant potential of the combined chemical−electrokinetic approach in the stabilization of soils of insufficiently good characteristics in their natural state, particularly in conditions of limited accessibility, deep landslides and densely populated urban areas. The proposed technique may find application in the design of infrastructure facilities, slope stabilization and soil remedition under existing facilities.
