Abstract

Diplomska naloga obravnava sanacijo plazu v Ravnah na Koroškem. Ker je diplomska naloga nastajala sočasno s procesom sanacije, ki je zajemal izvedbo geotehničnih raziskav, projektiranje sanacijskih ukrepov in izvedbo sanacije plazu, so v diplomski nalogi predstavljene vse faze projekta. Prvi del naloge opisuje geološke razmere na lokaciji, vključno z morfologijo terena in hidrogeološkimi razmerami. V nadaljevanju so predstavljeni rezultati terenskih in laboratorijskih preiskav, s katerimi smo definirali karakteristike tal na območju plazu. V geotehničnem laboratoriju UL FGG smo določili osnovne karakteristike zemljin, kot so: naravna vlaga, zrnavostna sestava, meje židkosti in plastičnosti in drenirana strižna trdnost. V drugem delu naloge je izvedena numerična analiza stabilnosti terena v prvotnem stanju in izdelan predlog in preverba sanacijskih ukrepov. Predlog sanacije obsega ukrep iz lesenih pilotov in oblic za zagotavljanje stabilnosti zgornjega dela pobočja, podporno konstrukcijo iz kamna v betonu za zagotavljanje stabilnosti spodnjega dela pobočja in koritnice za odvajanje površinske vode nad pobočjem. Poleg tega obsegajo sanacijski ukrepi polaganje kokosovega pletiva in izdelavo popletov na pobočju. Rezultati analiz potrjujejo mejno stanje stabilnosti pobočja v začetnem stanju ter ustreznost in zadostno stopnjo zagotavljanja varnosti predvidenih ukrepov za zagotovitev stabilnosti pobočja.

Secondary title:	Soil properties in the landslide area in Koroška with remediation proposal
Secondary abstract:	The thesis addresses the landslide remediation in Ravne na Koroškem. Since the thesis was developed simultaneously with the remediation process, which included geotechnical investigations, the design of remediation measures and the execution of the landslide remediation, all phases of the project are presented in the thesis. The first part of the thesis describes the geological conditions at the site, including terrain morphology and hydrogeological conditions. The following sections present the results of field and laboratory investigations, which were used to define the soil characteristics in the landslide area. In the geotechnical laboratory at UL FGG, we determined the basic soil characteristics, such as natural moisture content, grain size distribution, liquid and plastic limits, and drained shear strength. The second part of the thesis includes a numerical stability analysis of the terrain in its original state, as well as the proposal and verification of the remediation measures. The remediation measures include the use of timber piles and wooden logs to ensure the stability of the upper part of the slope, a retaining structure constructed from stone masonry in concrete for stabilizing the lower part of the slope, and surface water drainage channels above the slope. Additionally, the remediation measures include the installation of coconut fiber mesh and the implementation of brushwood fascines on the slope. The results of the analyses confirm the ultimate limit state of slope in its initial state and the adequacy and sufficient safety level of the proposed measures to ensure slope stability.
