Abstract:V diplomskem delu obravnavamo stabilnost in stabilizacijo neskončnega pobočja pri statični in potresni obtežbi. Namen dela je pokazati, kako na stabilnost vplivajo podzemna voda, potresni vpliv in izbrani stabilizacijski ukrepi ter kateri ukrep je pri enakih izhodiščnih pogojih najučinkovitejši. V programu Microsoft Excel smo izdelali deterministični računski model, ki iz enotnega nabora vhodnih podatkov določa faktor varnosti, kritično globino ter potreben obseg stabilizacije z izkopom, drenažo in sidranjem. Potresni vpliv je upoštevan psevdostatično z obema smerema navpičnega potresnega koeficienta. Računski primer je pokazal zmanjšanje faktorja varnosti z 0,8590 v statičnem stanju na najmanj 0,6516 pri potresu, kritična globina pa se je zmanjšala s 3,3601 m na 1,3812 m. Izkop je ciljni faktor varnosti dosegel šele pri posegu, večjem od 7,5 m, drenaža pa kot samostojen ukrep ni zadoščala. Najugodnejše se je izkazalo sidranje, pri katerem je zahtevana potresna sila 253,48 kN manjša od projektne odpornosti izbranega sidra 253,64 kN. Rezultati pokažejo, da izbira stabilizacijskega ukrepa ni odvisna le od doseženega faktorja varnosti, temveč tudi od potrebnega obsega in izvedljivosti posega.

Title:Stability and stabilization of an infinite slope under seismic loading
Abstract:This thesis examines the stability and stabilization of an infinite slope under static and seismic loading. The aim is to show how groundwater, seismic effects and selected stabilization measures influence slope stability and which measure is most effective under the same initial conditions. A deterministic model was developed in Microsoft Excel to determine the factor of safety, critical depth and the required extent of stabilization by excavation, drainage and anchoring from a common set of input data. Seismic loading is included using a pseudo-static approach with both signs of the vertical seismic coefficient. The case study showed that the factor of safety decreased from 0.8590 under static conditions to 0.6516 under seismic loading, while the critical depth decreased from 3.3601 m to 1.3812 m. Excavation achieved the target safety factor only with a cut exceeding 7.5 m, whereas drainage alone was insufficient. Anchoring proved to be the most suitable measure, with a required seismic anchor force of 253.48 kN, slightly below the design resistance of 253.64 kN. The results show that selecting a stabilization measure depends not only on the achieved factor of safety, but also on the required extent and feasibility of the intervention.
