Bredy, Somia ; Hodák,, Jiří (referee) ; Miča, Lumír (referee) ; Jandora, Jan (advisor)
This study focuses on the most important sealing technologies; Diaphragm walls and Jet grouting as a major most popular reliable option when it comes to engineering constructions rehabilitation. Those two methods have been used in Karolinka dam for reducing seepage through its body. Diaphragm walls were used along the dam, and jet grouting was used at both ends of the dam. The study deals with the possibility of numerical modelling of these two technologies. It is included how to carry out, interaction with adjacent soil, cement shrinkage, slope stability, changing of pore water pressure with the time, dynamic analysis of drilling rod and the effects of both technologies on slope stability, seepage and settlement of dam. This modelling was conducted with the finite element method based on software Plaxis 3D.
