Construction of embankments with steep slopes |
Sekundarni povzetek: |
The subject of this degree is different methods for construction of steep slopes. For long-term
stability and usefulness of the steep slopes it is necessary to provide additional support forces
to ensure safe construction and use of banks. For the safe construction and use of steep
slopes, I presented four possible variants of the retaining structures. I considered two types of
gravity retaining structures and retaining structures that rely on the reinforcement of soil. The
studied gravity retaining structures were the reinforced concrete gravity wall and gabions,
whereas retaining structures of reinforced soil included in thesis were the green reinforced
slope with forehead made from layer of humus and reinforced slope with forehead made of
concrete blocks. All four variants are presented, described and used in various practical
examples. Static analysis of all structures were made according to the German guidelines
(EBGEO), British reference guide for designing of mass gravity gabion walls based on
British standard BS8002 and the Eurocode 7 for concrete gravity wall. For all cases relevant
ultimate limit states and global stability were checked. The serviceabillity limit state (control
of displacements) was analysed by FEM using Plaxis code. The results were compared and
discussed. Final remarks on individual type of construction of embankment with steep slopes
are given. |

V diplomski nalogi sem obravnaval načine gradnje strmih brežin. Za dolgotrajno stabilnost in
uporabnost strmih brežin je potrebno zagotoviti dodatne podporne sile, ki zagotavljajo varno
gradnjo in uporabo brežin. Za varno gradnjo in uporabo strmih brežin sem predstavil štiri
možne variante podpornih konstrukcij. Obravnaval sem dve vrste težnostnih podpornih
konstrukcij ter podporne konstrukcije, ki so izvedene s pomocjo armiranja zemljin. Težnostni
podporni konstrukciji sta armirano betonski podporni zid in podporni zid izveden z gabioni,
podporni konstrukciji iz armiranih zemljin pa sta armirana brežina z zatravljenim celom
brežine in armirana brežina s celom iz betonskih blokov. Vse štiri variante sem predstavil in
opisal ter jih obravnaval v razlicnih primerih gradnje. Računske primere sem računal s
pomočjo nemških smernic (EBGEO), priporočil za izračun stabilnosti podpornih konstrukcij
iz gabionov, ki so zasnovani na britanskem standardu BS8002 ter z Evrokodom 7. Pri
računskih primerih sem obravnaval možne lokalne in globalne porušitve ter pomike brežin.
Kontrolo pomikov sem izvedel z računalniškim programom PLAXIS. Dobljene rezultate sem
primerjal ter podal svoje zaključno mnenje za posamezen način gradnje strmih brežin. |
