Stone columns - importance of arch effect
Vanko, Peter ; Zdražil, Karel (referee) ; Miča, Lumír (advisor)
The aim of the the thesis is to study the development of arch effect depending on the change of the various parameters such as grid of columns, height of embankments, material of embankment fill and material of columns. The first phase of work summarizes theoretical knowledges of stone columns and arch effect. The next phase deals with analysis of the effect of arch using numerical modeling. In the next part of the second phase circular tank based on stone columns will be modeled, where deformations and stress on columns will be monitored in changing constitutive model and applying substitute characteristics. Obtained results will be evaluated in conclusion.

Time depending analysis of subsoil reinforced by stone columns
Vykoukal, Libor ; Doněk,, Michal (referee) ; Miča, Lumír (advisor)
The thesis focuses on the time analysis of the subsoil which is reinforced with stone columns and without them. The subsoil is made of saturated clays. Main purpose is to introduce the improvement into the numerical models. For the purpose of the diploma thesis the software Plaxis has been chosen, which is normally used for geotechnical tasks. The influence of the stone columns have been introduce to the model using the drain elemnets, spare charakteristics and local elements.
