Abstract

Analiza obnašanja konstrukcij dandanes predstavlja pomembno področje gradbene stroke. Monitoring kot ena izmed praktičnih možnosti analize v najširšem smislu povzema kontinuirano opazovanje in izvajanje meritev izbranih parametrov za določen cilj skozi daljše časovno obdobje. V gradbeništvu, kjer nas zanima predvsem odziv konstrukcije na določene vplive, monitoring gradbenih konstrukcij zajema analizo pomikov, deformacij in drugih parametrov, ki bi v svoji osnovi lahko imele potencialni vpliv na konstrukcijo. Magistrsko delo z naslovom »Sinhronizacija geodetskih in fizikalnih meritev pri izvedbi monitoringa Studenške brvi« temelji na teoretičnih osnovah monitoringa gradbenih konstrukcij s pomočjo geodetskih in fizikalnih metod ter obravnava praktično analizo odziva konstrukcije na različne umetno povzročene obtežne slučaje. Odzive konstrukcije smo skozi različne parametre, kot so pomik, hitrost in pospešek, beležili s pomočjo geodetske (RTS in GNSS) in fizikalne opreme (triaksialni geofoni). Pri uporabi geodetske opreme nas je poleg možnosti končne sinhronizacije rezultatov zanimal tudi dejanski vpliv frekvence zajema podatkov na natančnost izmerjenih vrednosti. V nasprotju s slednjimi smo pri ločeni analizi odziva konstrukcije s fizikalnimi metodami analizirali predvsem možnost sinhronizacije izmerjenih signalov s stališča pripadajočih hitrosti in pospeškov konstrukcijskega odziva. Posebno poglavje smo posvetili tudi predstavitvi spektralne analize s teoretičnega vidika, le-temu pa smo skozi obdelavo podatkov z uporabo algoritmov Fourierjeve transformacije dodali tudi praktično vrednost.

Secondary title:	Synchronization of geodetic and physical measurements in the implementation of Studenška brv monitoring
Secondary abstract:	Nowadays, an analysis of construction movements represents an important area of civil engineering. Monitoring of civil engineering structures, as one of the practical possibilities of analysis, in the broadest sense summarizes the continuous observation and measurements of the selected parameters for a definite goal over a long period of time. In civil engineering, where we are mainly interested in the response of the structure to certain influences, monitoring mainly involves the analysis of displacements, deformations and other parameters that could have a potential impact on the construction in its entirety. The master thesis titled "Synchronization of geodetic and physical measurements in the implementation of Studenška brv monitoring" is based on the theoretical principles of monitoring performed on civil engineering structures using geodetic and physical methods and deals with the practical analysis of the construction response to artificially caused loads. Construction response was determined through various parameters such as displacements and speed as well as acceleration, with usage of geodetic (RTS and GNSS) and physical (triaxial geophones) equipment. In addition to the potential possibility of final synchronization of results when using geodetic equipment, we were also interested in the potential effect of selected frequency regarding the accuracy of the measured values. Considering the analysis with physical methods, we above all analysed the possibility of synchronizing the measured signals via corresponding speeds and accelerations of the structural response. A special chapter was devoted to the presentation of spectral analysis from a theoretical point of view, which was given a practical value through the processing of data using the Fourier transform algorithms.
