20.500.12556/RUL-186467 Geodetska mreža za horizontalno spremljanje stabilnosti opornih zidov diplomska naloga Geodetic network for horizontal monitoring of retaining wall stability graduation thesis V diplomski nalogi obravnavamo projektiranje, vzpostavitev, izmero in obdelavo geodetske mreže za horizontalno spremljanje stabilnosti opornega in podpornega zidu ob regionalni cesti R2-408/1375 Žiri– Trebija v naselju Selo. Mrežo sestavljajo tri referenčne točke, sedem stojišč in 38 kontrolnih točk, stabiliziranih na obeh zidovih. Izvedli smo 0. in 1. izmero s preciznim elektronskim tahimetrom Leica Geosystems Nova TS60 po girusni metodi. Meritve smo predhodno obdelali, reducirali izmerjene dolžine, izračunali višinske razlike ter izvedli horizontalno izravnavo proste in vpete mreže ter višinsko izravnavo. S primerjavo koordinat in višin med obema izmerama smo določili horizontalne in višinske premike kontrolnih točk ter ob upoštevanju pripadajočih standardnih odklonov presodili njihovo značilnost. Dosežena položajna natančnost kontrolnih točk je bila boljša od 2 mm, povprečni položajni standardni odklon pri vpeti izravnavi pa je znašal približno 0,5 mm. Horizontalni premiki so znašali od približno 0,7 mm do 4,4 mm, kot statistično značilni pa so bili ocenjeni pri 31 od 38 kontrolnih točk. Značilen višinski premik je bil ugotovljen samo na kontrolni točki 8, vendar je uporabljeni kriterij presegel le minimalno. Zaradi velike temperaturne razlike med izmerama in izvedbe samo dveh izmer ugotovljenih sprememb še ni mogoče zanesljivo opredeliti kot trajne premike. Vzpostavljena mreža predstavlja ustrezno osnovo za nadaljnji geodetski monitoring obeh zidov. In this thesis, we present the design, establishment, surveying and processing of a geodetic network for horizontal monitoring of the stability of a retaining wall and a supporting wall along the regional road R2-408/1375 Žiri–Trebija in the settlement of Selo. The network consists of three reference points, seven instrument stations and 38 control points stabilised on the two walls. A zero-epoch and a firstepoch survey were carried out using a Leica Geosystems Nova TS60 precision total station and the sets of angles method. The observations were pre-processed, the measured distances were reduced, and height differences were calculated. Free and constrained horizontal network adjustments and a vertical network adjustment were then performed. By comparing the coordinates and heights obtained from both epochs, horizontal and vertical displacements of the control points were determined, and their significance was assessed by considering the corresponding standard deviations. The achieved positional accuracy of the control points was better than 2 mm, while the mean positional standard deviation obtained from the constrained adjustment was approximately 0.5 mm. The horizontal displacements ranged from approximately 0.7 mm to 4.4 mm and were assessed as statistically significant at 31 of the 38 control points. A significant vertical displacement was detected only at control point 8; however, the adopted significance criterion was exceeded only marginally. Due to the large temperature difference between the two surveys and the availability of only two measurement epochs, the detected changes cannot yet be reliably classified as permanent displacements.
