Abstract

Pri projektiranju podpornih zidov v praksi le redkokdaj izvajamo detajlno analizo potresnih vplivov; če že, se poslužujemo konservativnih poenostavitev. V pričujočem diplomskem delu je predstavljen celostni pristop geotehnične analize AB podpornega zidu. Najprej je obdelana stabilnost pod statičnimi pogoji v skladu z EN 1997-1, nato pa sta primerjani dve metodi analize seizmičnih vplivov; psevdo-statična, kot jo priporoča EN 1998-5 ter dinamična, kot sta jo predlagala Chowdhury in Dasgupta (2009b). Slednja je obravnavana v dveh delih; najprej pod predpostavko, da je zid togo vpet v tla, nato pa še z upoštevanjem dinamične interakcije objekt-zemljina (Chowdhury, 2011). Primerjava rezultatov obeh seizmičnih analiz na izbranem primeru je pokazala podobne vrednosti notranjih statičnih količin pridobljenih s psevdo-statično ter prvim delom dinamične metode, medtem ko vrednosti dobljene z drugim delom dinamične metode nekoliko odstopajo in so se izkazale kot maksimalne.

Secondary title:	Geomechanical analysis of a RC retaining wall considering seismic actions
Secondary abstract:	A detailed analysis of seismic effects is rarely carried out while designing retaining walls and if so, conservative simplifications are used. In the following thesis a complete approach to geotechnical analysis of a RC retaining wall is presented. Firstly the stability under static conditions in accordance with EN 1997-1 is considered, followed by a comparison of two distinct methods of seismic analysis, namely the pseudo-static analysis, as recommended by EN 1998-5 and a dynamic analysis as proposed by Chowdhury and Dasgupta (2009b). The later is dealt with in two parts; in the beginning it is assumed the wall is fixed in the ground and in the second part the dynamic soil-structure interaction is considered (Chowdhury, 2011). Result comparison on a worked example has shown similar values of shear and moments obtained with the pseudo-static and the first part of the dynamic analysis, while the values obtained with the second part of the dynamic analysis slightly differ and represent the maximum values.
