20.500.12556/RUL-159031 Analiza konstrukcij iz armirane zemljine po predlogu standarda Evrokod prEN 1997-3 diplomska naloga Analysis of reinforced fill structures according to the proposal of the Eurocode standard prEN 1997-3 graduation thesis Pred izdajo novega predstandarda Evrokod 7 konec leta 2022 je bila armirana zemljina zajeta v nemških smernicah EBGEO, ki so jih projektanti velikokrat kombinirali z Evrokodom 7:2005. Novi predstandard EC7:2022 vključuje poglavje o armirani zemljini, vendar način dokazovanja varnosti geotehničnih konstrukcij definira drugače kot EBGEO. V diplomski nalogi smo na konkretnem primeru armiranega nasipa primerjali potrebne dolžine in natezne nosilnosti armaturnega geosintetika po treh standardih: EC7:2005, EBGEO in EC7:2022. Ugotovili smo, da so formalne razlike v postopkih minimalne, prav tako se izračunane dolžine geomrež le malo razlikujejo. Opazna pa je razlika pri izračunu potrebne natezne trdnosti geosintetika, kjer nov evrokod predpisuje manjši delni faktor varnosti za mehansko odpornost geosintetikov �� (1,1) kot EBGEO (1,4), kar vpliva na rezultate dimenzioniranja. Before the new Eurocode 7 pre-standard was issued at the end of 2022, reinforced soil was covered by the German EBGEO guidelines, which designers often used in combination with Eurocode 7:2005. The new pre-standard EC7:2022 includes a chapter on reinforced soil, but also defines the approach of proving the safety of geotechnical constructions differently from EBGEO. In the thesis, we compared the required lengths and tensile strengths of the reinforcement geosynthetics according to the three standards EC7:2005, EBGEO, and EC7:2022, using a specific example of a reinforced embankment. We found that the formal differences in procedures were minimal, and the calculated lengths of geogrids differed only slightly between the three standards. However, a noticeable difference arises in the calculation of the required tensile strength of geosynthetics, where the new Eurocode prescribes a smaller partial safety factor for the mechanical resistance of geosynthetics �� (1.1), compared to EBGEO (1.4), affecting the dimensioning results. gradbeništvo diplomske naloge UNI GR B-GR EBGEO EC7:2005 EC7:2022 armirana zemljina podporne konstrukcije graduation thesis civil engineering reinforced fill structure retaining structures true false false [D.
