In the paper, two independent methods of deformation analysis are applied on the example of the Ratkov Laz bridge in Montenegro, based on two epochs of geodetic measurements in a 3D geodetic network, which consists of the reference part of the network and points on the bridge. The results of the Pelzer’s method and the robust IWST method were analyzed. Although similar displacement vectors are obtained using the two methods, there are some differences in the identification of unstable points on the bridge. The IWST method identified significantly fewer points as unstable compared to the Pelzer’s method. The aforementioned methods of deformation analysis are of great importance in the geodetic observation of all types of engineering facilitiesV prispevku je obravnavana uporaba geodetskih metod deformacijske analize armiranobetonskih konstrukcij iz prednapetega betona. Na primeru mostu Ratkov Laz v Črni gori sta uporabljeni dve neodvisni metodi deformacijske analize na podlagi dveh epoh geodetskih meritev v 3D-geodetski mreži, ki je sestavljena iz referenčnega dela mreže in točk na mostu. Analizirani so bili rezultati Pelzerjeve metode (postopka Hannover) in robustne metode IWST. Čeprav so z obema metodama izračunani podobni vektorji pomikov, obstajajo nekatere razlike pri identifikaciji nestabilnih točk na mostu. Z metodo IWST je bilo kot nestabilnih identificiranih precej manj točk kot s Pelzerjevo metodo. Opisani metodi deformacijske analize sta zelo pomembni pri geodetskem opazovanju vseh vrst inženirskih objektovTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza geodetov Slovenije
