This article presents the deformation analysis according to the Munich approach of W. M. Welsch. The method deals with the testing of the geodetic network's congruence, the affinity of selected triangles, and the testing of other kinematic parameters in 2D geodetic networks. Deformation analysis using the Munich approach can be performed using the X-method, which is based on the comparison of the coordinates of identical points in the geodetic network between two sets of measurements that depend on the geodetic datum, or using the L-method, which determines changes in the values of lengths and angles which are quantities independent of the geodetic datum. In the modified method, we propose to determine the congruence of all lengths and all angles in the network between two sets of measurements and to determine the congruence of all triangles between points in the network, not only selected ones, as it is common in the classical approach of deformation analysis based on the Munich approach. The proposed improvements are tested on the example of a known hexagon, and an analysis is made of the success of detecting stable points in the network using the classical Munich approach. In the present case, the results of the proposed method did not differ from the results of other deformation analysis methodsKljub tehnološkemu napredku v stroki ostaja spremljanje stabilnosti gradbeno-inženirskih objektov ena zahtevnejših nalog v inženirski geodeziji. V članku obravnavamo deformacijsko analizo po postopku München, ki jo je predlagal W. M. Welsch. Metoda obravnava testiranje skladnosti geodetske mreže, testiranje preoblikovanja izbranih trikotnikov in testiranje kinematičnih parametrov v 2D-geodetskih mrežah. Deformacijsko analizo po postopku München lahko izvedemo z metodo X, ki temelji na primerjavi koordinat identičnih točk v geodetski mreži med dvema terminskima izmerama, ki so odvisne od geodetskega datuma, ali z metodo L, s katero se ugotavljajo spremembe vrednosti dolžin in kotov, ki so od geodetskega datuma neodvisne količine. V modificirani metodi predlagamo ugotavljanje skladnosti vseh dolžin in vseh kotov v mreži med dvema terminskima izmerama ter ugotavljanje skladnosti vseh trikotnikov med točkami v mreži, ne le izbranih, kot je običaj pri klasičnem pristopu deformacijske analize po postopku München. Predlagane izboljšave testiramo na primeru znanega šestkotnika in izdelamo analizo uspešnosti odkrivanja stabilnih točk v mreži glede na klasični pristop metode München. Rezultati predlaganega postopka se na obravnavanem primeru niso razlikovali od rezultatov drugih postopkov deformacijske analizeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza geodetov Slovenije
