Abstract

Diplomsko delo vsebuje obravnavo plazu v vasi Planina pod Golico v občini Jesenice. Nestabilno pobočje je močno poškodovalo lokalno cesto na odseku dolžine cca. 45 metrov, ki je v zimskih mesecih edina povezava z Jesenicami. V začetku diplomskega dela je predstavljena lokacija, poškodbe cestišča, osnovne dimenzije plazu ter začasna sanacija cestnega odseka, zgrajena pred 8 leti. Na podlagi geotehničnih raziskav iz štirih sondažnih vrtin so v nadaljevanju diplomskega dela predstavljene materialne lastnosti zemljin in kamnin ter nivo podzemne vode na tem območju. Pridobljeni podatki jeder vrtin so služili kot osnova za povratno analizo, kjer smo iskali natančnejše vzroke splazitve. Analiza je vsebovala dve možni varianti, za sprožitev plazu in sicer: nizek nivo podzemne vode in slabe materialne karakteristike ter visok nivo podzemne vode in boljše materialne karakteristike. Pomagali smo si s sodobno programsko opremo – programom Slide 6.0. Iz ugotovitev povratne analize in geodetskega načrta se je izdelalo predlagani sanacijski načrt, na zgornji strani ceste armiranobetonski oporni zid, na spodnji pa sidrana pilotna stena, ki bo zagotavljala globalno stabilnost pobočju. Izračuni dimenzij so izvedeni skladno s standardom Evrokod 7. Na koncu je prikazana še globalna varnost območja po sanaciji, kjer pa so našteti tudi dodatni ukrepi za izboljšanje stabilnosti. Med le-te spada ureditev odvoda zaledne vode in ponovna pogozditev prizadetega območja.

Secondary title:	Remediation of Planina pod Golico landslide
Secondary abstract:	The main intention of this diploma work was to present the remediation of the landslide in the Planina pod Golico village, located within Jesenice community. Unstable slope heavily damaged approx. 45 metres long part of the local road which is the only connection to Jesenice in winter months. There are location, road damage, basic dimensions of the landslide and temporary rehabilitation of the road, built 8 years ago, presented in the beginning of the thesis. In the continuation of this thesis the material properties of soils and rocks are described, based on geotechnical studies of four probe holes. What is more, there is also information about the level of groundwater in this particular area. The acquired data from probe holes were used as the basis for feedback analysis, through which we were searching for more exact reasons for the landslide. The analysis contains two possible variants to trigger an avalanche. First one is: a low level of groundwater and poor material properties followed by a high level of groundwater and improved material properties. Modern software-program Slide 6.0 was used for research. From the results of the feedback analysis and the geodetic plan, the proposed recovery plan was made. It suggests reinforced concrete retaining wall on the upper side of the road and an anchored pile wall on the lower side in order to provide global stability of the slope. Calculated dimensions were carried out in accordance with the standards of Eurocode 7. In conclusion, there is a description of global security of this area after redevelopment and what is more, the thesis also suggests some additional measures to improve its stability. Among these measures belong also draining of the water and reforestation of the affected area.
