Sekundarni naslov:	Defining displacements of bridges with geodetic methods on an example of a highway bridge Freimann in Germany
Sekundarni povzetek:	These theses discuss a highway bridge Freimann in Germany. This is around 600 m long and up to 40 m wide bridge in Munich. Because of necessary renovation was bridge longitudinal sawn into two parts. This procedure lasted 20 days. Whole length was divided on 20 spans. Discussed are data for length between three successive spans. Work on this area last two days. Measured were seven time cycles. Described is preparation on geodetic survey, course of survey, analyses of results and deformation measurements. For signalization of points on the bridge were used targets with reflective tape. Suitability of those targets for deformation measurements was fully analyzed. Additionally to other observations was defined geometry of targets, which was considered in adjustment procedure. Compared were results of adjustment in network with and without consideration of geometry of retro targets. On retro targets was researched relative accuracy of adjusted coordinates. Deformation analysis was made using method Hannover. Compared were seven time cycles and results were graphically shown.

Povzetek (ePrints):	Diplomska naloga obravnava avtocestni most Freimann v Nemčiji. To je približno 600 m dolg in do 40 m širok most v Münchnu. Zaradi nujne obnove mostu je bil most vzdolžno prepolovljen. Celoten postopek je trajal 20 dni. Celotna dolžina mostu je bila razdeljena na dvajset razpetin. V nalogi so obravnavani podatki treh razpetin. Delo je na tej dolžini trajalo dva dni. Izmerjenih je bilo sedem časovnih ciklov opazovanj. Opisana je priprava na meritve, potek meritev in analiza dobljenih podatkov ter deformacijska analiza. Za signalizacijo točk na mostu so bile uporabljene tarče z odbojno folijo (retro tarče). Primernost teh tarč za deformacijska merjenja je bila natančno analizirana. Dodatno k podatkom meritev na terenu je bila določena in upoštevana geometrija retro tarč. Primerjani so bili rezultati izravnave mreže z in brez upoštevanja geometrije retro tarč. Na retro tarčah je bila raziskana tudi relativna natančnost izravnanih koordinat. Za deformacijsko analizo je bila uporabljena metoda Hannover. Primerjanih je bilo sedem časovnih ciklov, rezultati pa so bili tudi grafično prikazani.
