Abstract
Ukrepe zavarovanja izkopov s podpornimi konstrukcijami, se dandanes pogosto preverja z numeričnimi analizami, vendar pa se pri obravnavi enostavnih podpornih konstrukcij v nezahtevnih pogojih včasih še vedno uporablja analitične postopke. V diplomski nalogi je na primeru enostavne sidrane zagatne stene s polnili opravljena primerjava analitičnih in numeričnih postopkov. V analitičnih analizah se vplivi na konstrukcijo upoštevajo kot deterministično določeni zemeljski pritiski oziroma odpori. Pri določanju pasivnega odpora zemljine, ki deluje na vpeti dolžini konstrukcije, je na voljo več različnih postopkov. Za pridobitev večjega nabora rezultatov za primerjavo so računske analize opravljene za različne vrednosti strižne trdnosti zemljine in razmaka nosilnih gred oziroma pilotov. Rezultati pridobljeni z analitičnimi izračuni po različnih metodah so na koncu primerjani še z vrednostmi določenimi z numerično analizo modela podporne konstrukcije po metodi končnih elementov.

Title:Numerical analysis of anchored soldier pile wall : graduation thesis
Abstract:
The supporting structures for deep excavations are nowadays often verified by numerical analyses, but sometimes, when dealing with simple structures in undemanding ground conditions, analytical procedures are still used. In this diploma thesis, the comparison of analytical and numerical procedures is presented on an example of anchored soldier wall. In the analytical analyses the actions on structures are determined deterministically based on active earth pressures and passive earth resistances. Several different procedures are available for determining the passive resistance of the soil acting on the embedded length of structure. In order to obtain a larger set of results for comparison, computational analyzes are performed for different shear strength of soil and spacings of bearing beams or piles. The results obtained by analytical calculations using different methods are finally compared with the values determined with the numerical analysis of supporting structures using the finite element method.

Keywords:Soldier pile wall, active earth pressure, spatial passive earth pressure, spatial earth pressures according to Blum’s procedure, DIN 4085, numerical analysis, Plaxis 2D
