Abstract

Ovaj diplomski rad istražuje značaj kriterija osjetljivosti u geodetskim
mrežama namijenjenim praćenju pomaka i deformacija. Kriterij osjetljivosti
određuje minimalnu vrijednost pomaka koju projektirana geodetska mreža može
detektirati u smjeru od interesa. U radu se naglašava važnost praćenja pomaka i
deformacija te postavljanja geodetske mreže u te svrhe, uz detaljno objašnjenje
deformacijske analize po Hannover metodi. Hannover metoda stvara temelj za
razumijevanje procesa analize osjetljivosti, uključujući definiciju datuma, kriterij
preciznosti i statističko testiranje. Zaključno, provedena je a priori analiza
osjetljivosti za različite geometrijske konfiguracije, planove opažanja i
preciznosti instrumenata unutar geodetske mreže. Podaci su obrađeni i
analizirani u Microsoft Excelu, a grafički interpretirani u AutoCAD softveru.
Rezultati analize su od esencijalne važnosti za pravilno projektiranje i
optimizaciju geodetske mreže, osiguravajući njezinu sposobnost učinkovitog
praćenja pomaka i deformacija na terenu.

Abstract (english)

This master's thesis delves into the significance of sensitivity criteria in
geodetic networks designed for monitoring displacements and deformations. The
sensitivity criterion determines the minimum displacement value that the network
can detect in the direction of interest. The paper underscores the importance of
monitoring displacements and deformations, as well as establishing a geodetic
network for these purposes, while providing a detailed explanation of
deformation analysis using the Hannover method. The Hannover method lays the
groundwork for understanding the sensitivity analysis process, encompassing the
definition of datum, precision criteria, and statistical testing. In conclusion, an a
priori sensitivity analysis was conducted for various geometric configurations,
observation plans, and instrument precisions within the geodetic network. Data
were processed and analyzed in Microsoft Excel, with graphical interpretation
facilitated through AutoCAD. The results of the analysis are paramount for the
proper design and optimization of the geodetic network, ensuring its capability
for effectively monitoring displacements and deformations in the field.
