Ovim radom su prikazane teorijske osnove dimenzioniranja i primjer proračuna potpornog zida. U prvom dijelu se daje uvid u opterećenja koja djeluju na potporne konstrukcije te osnovna načela projektiranju prema Eurokodu, zajednička za sve vrste potpornih zidova. U praktičnom djelu rada, na primjeru armiranobetonskog konzolnog potpornog zida visine 4 m, prikazan je postupak proračun na statička i seizmička djelovanja, primjenom Europskih normi za geotehničko projektiranje, EN 1997-1 i projektiranje konstrukcija otpornih na potres, EN 1998-5. Za ostale visine potpornih zidova definiranih zadatkom, zbog opsežnosti i ograničenog prostora rada, prikazani su samo rezultati proračuna u sklopu analize rezultata. Na kraju rada je dan zaključak analize provedenog proračuna. This paper presents the theoretical basis of dimensioning and an example of the calculation of a retaining wall. The first part provides an insight into the loads acting on the supporting structures and the basic design principles according to the Eurocode, common to all types of retaining walls. In the practical part of the paper, on the example of a reinforced concrete cantilever retaining wall with a height of 4 m, the calculation procedure for static and seismic actions is presented, using the European standards for geotechnical design, EN 1997-1 and the design of structures for earthquake resistance, EN 1998-5. For the other heights of the supporting walls defined by the task, due to the extensiveness and limited space of the paper, only the calculation results are presented as part of the analysis of the results. At the end of the paper, the conclusion of the analysis of the implemented budget is given. |
