Analiza sanacije plazu in možnost rabe izkopanih zemljin za preoblikovanje terena na lokaciji : diplomska naloga

Tavčar, Meta Katarina (author), Logar, Janko (mentor), Smolar, Jasna (co-mentor)

Diplomsko delo obravnava sanacijo plazu Lajše v občini Železniki. V danem primeru gre za ožje nestabilno območje, ki se vidno premika v dolžini cca. 70 m, kar se na cesti odraža kot posedanje, na travniku pod cesto pa kot izrivi. V prvem delu diplomskega dela je predstavljeno teoretično ozadje sanacije plazu, opisani sta programska oprema, s katero je bila izvedena povratna stabilnostna analiza obstoječega stanja terena, in okoljska ter gradbena zakonodaja, s katero se v praksi srečamo pri sanacijskih ukrepih. V drugem delu diplomskega dela so predstavljene materialne karakteristike zemljin in kamnin, nivo podzemne vode ter merjeni pomiki na tem območju, identificirani z geološko geomehanskimi raziskavami. Pridobljeni podatki iz vrtin so služili kot osnova za povratno stabilnostno analizo, ki je bila narejena s programsko opremo Slide 9.0. Na podlagi rezultatov analize je bila predlagana sanacijska rešitev z armiranjem brežine med profili P1-P20, medtem ko bi med profili P20-P30 ostala predlagana projektantova rešitev sidrane pilotne stene. V diplomski nalogi so bili izvedeni tudi izračuni količin zemeljskega izkopa za sanacijska dela ter ocenjene količine nastalih gradbenih odpadkov.

Abstract

Graduation thesis deals with the remediation of the Lajše landslide in the municipality of Železniki. The landslide has a form of 70 m long and narrow unstable area with visible surface deformations, which cause settlements of a local road sitting on the top of the landslide. The first part of the thesis presents the theoretical background of landslide remediation including a description of the software used for the stability analyses of the present and designed state. Furthermore, the relevant environmental and construction legislation is presented. The second part of the thesis presents the material characteristics of soils and rocks, groundwater level and measured displacements in this area, identified by geological and geomechanical investigations. The data obtained from the boreholes served as the basis for the stability back-analysis performed with the Slide 9.0 software. Based on the results of stability analysis, remediation measures were proposed in terms of reinforced embankment between the profiles P1-P20, while the original designer's solution utilizing anchored pile wall is adopted between the profile P20-P30. The quantities of earth excavation for remediation works and the estimated quantities of generated construction waste are also given in the thesis.
