Abstract
Diplomsko delo obravnava sanacijo plazu Šmihel pri Novi Gorici z armiranobetonskimi vodnjaki na podlagi izračunov po metodi končnih elementov. V prvem delu je predstavljena situacija plazu in zbrani rezultati terenskih in laboratorijskih preiskav. Z vrednotenjem standardnih penetracijskih preizkusov in laboratorijskih preiskav so določene materialne karakteristike temeljnih tal. Drugi del naloge obravnava numerično modeliranje po metodi končnih elementov v dvo (2D) in tridimenzionalnem okolju (3D) in izračun obremenitev vodnjaka. S primerjavo rezultatov računskih analiz so ocenjene prednosti in slabosti 2D in 3D analiz, prav tako je prikazan vpliv drenaž na globalno stabilnost pobočja in obremenitve armiranobetonskega vodnjaka. Z obremenitvami iz nelinearne numerične analize so dimenzionirani posamezni kritični prerezi konstrukcijskih elementov armiranobetonskega vodnjaka, ki služijo kot osnova za izris armaturnih načrtov.

Title:Comparison of 2D and 3D geotechnical analysis of reinforced concrete shafts for the mitigation of Šmihel landslide
Abstract:
The thesis presents the rehabilitation of Šmihel landslide. In the process reinforced concrete shafts were used. The mitigation was based on the numerical finite element method analysis. In the first part the landslide situation is presented along with field and laboratory tests. On the basis of SPT and laboratory tests, mechanical properties of soils are determined and used in the numerical analysis. The second part of the thesis presents the modelling and calculation of the landslide in 2D and 3D working environment. The comparison of the results shows the advantages and disadvantages of 2D and 3D analysis. The influence of the drainage on global stability and loading of the structure is also taken into consideration. Internal forces calculated with the numerical analysis are used for dimensioning of steel reinforcement in critical cross sections, which is the basis for drawing detailed reinforcement plans.

Keywords:graduation thesis, Landslide Šmihel, SPT, reinforced concrete shafts, slope stability, finite element analysis, nonlinear analysis
