diplomska naloga
Abstract
Diplomska naloga obravnava probleme zagotovitve optimalne geometrije terestričnih geodetskih mrež za potrebe periodičnega spremljanja premikov in deformacij geotehničnih objektov. Obravnavane so geodetske mreže savskih hidroelektrarn Moste, Mavčiče, Vrhovo in Boštanj. Pri iskanju optimalne geometrije je bila uporabljena metoda optimizacije geodetskih mrež s poskušanjem. Metoda temelji na izvajanju računalniških simulacij meritev v mrežah. Za vsako obravnavano mrežo so bile na podlagi rezultatov meritev zadnjih terminskih izmer določene dodatne opazovalne točke mreže. Za vsako varianto v posamezni mreži je bila izvedena izravnava simuliranih meritev po razširjeni metodi najmanjših kvadratov. Rezultati kažejo, da večina obravnavanih mrež že ima optimalno geometrijo, ki zagotavlja ustrezno natančnost izmere in zato praktično ne potrebuje izboljšav.

Secondary title: |
Selecting the optimal geometry of terrestrial geodetic networks for deformation surveys of the dams of hydroelectric plants |
Secondary abstract: |
In this graduation thesis the problem of assuring the optimal geometry of terrestrial positional geodetic networks, established for periodical deformation surveys of geotechnical objects, is discussed. In particular, four geodetic networks, established for monitoring the dams of hydroelectric plants Moste, Mavčiče, Vrhovo and Boštanj on Sava river are analysed. To find the optimal geometry of discussed networks the "trial and error" method of network optimization was used. This method is based on computer simulations of measurements. For every discussed geodetic network we defined additional reference points, which were selected on the basis of the results of previous measurements in these networks. For every variant of each discussed geodetic network simulated measurements were adjusted using the extended method of least squares. Results show that most of the discussed geodetic networks already have optimal geometry and don't necessarily need improvements. |
