Secondary title:	Determination of vertical displacements of benchmarks on the building of the University of Ljubljana
Secondary abstract:	This thesis presents the determination of vertical movements of facility of the University of Ljubljana. The measurements which were carried out were performed in three epochs. For the measurements the digital level Leica DNA03 and the precision levelling invar with bar code Leica GPCL2 were used. Observations were offset by indirect levelling. We got leveled heights of the benchmarks and the precision for the determination of benchmarks. For the determination and movement analysis of benchmarks we used the programme DAH - Hannover strain analysis and programme PremikWin1. The programme PremikWin1 assumes the benchmarks as stable, if the movement is less than three times lower than the precision of the determination of vertical movement. Hannover strain analysis is a procedure which detects and determines the resulting movements with the method of statistical analysis. With this procedure we test the homogeneity of the accuracy of epochs, and perform a global test of network consistency between the two epochs and test the eventual movements on the observed object. In the thesis the both processes were presented and compared.

Abstract (ePrints):	V diplomski nalogi je predstavljeno določanje vertikalnih premikov reperjev stavbe Univerze v Ljubljani. Meritve, ki smo jih izvedli, so potekale v treh terminskih izmerah. Pri izmerah smo uporabljali precizni nivelir Leica DNA03 in precizni kodirani invar nivelmanski lati Leica GPCL2. Opazovanja smo izravnali s posredno izravnavo. Dobili smo izravnane višine reperjev in natančnosti določitve višin reperjev. Za določitev oziroma analizo premikov smo uporabili program DAH – deformacijska analiza Hannover in program PremikWin1. Program PremikWin1 privzame reperje za stabilne, če je premik manjši od trikratne vrednosti natančnosti določitve vertikalnega premika. Deformacijska analiza Hannover je postopek, ki odkrije in določi nastale premike z metodo statistične analize. Tako testiramo homogenost natančnosti terminskih izmer, opravimo globalni test skladnosti mreže med dvema terminskima izmerama in testiramo morebitne premike na opazovanem objektu. V nalogi smo predstavili oba postopka in ju med seboj primerjali.
