Geodetsko spremljanje stabilnosti pregrade Drtijščica na Gradiškem jezeru : magistrsko delo št.: 116/II. GIG

Letnar, Lara (author), Kogoj, Dušan (mentor), Kregar, Klemen (co-mentor)

V magistrski nalogi smo primerjali dve terminski izmeri geodetske mreže pregrade Drtijščica na Gradiškem jezeru. Prvo terminsko izmero smo izvedli aprila 2018, drugo pa konec meseca februarja 2020. Namen naloge je odkriti domnevno nestabilne točke mreže. Mreži smo izravnali kot prosti in s postopkom S-transformacije določili ustrezen geodetski datum mreže. V na novo določen geodetski datum smo vklopili mreži iz leta 2018 in nato še iz leta 2020. Mreži smo izravnali kot vpeti. Na podlagi izravnanih koordinat točk obeh terminskih izmer vpetih mrež smo določili morebitne statistično značilne premike točk mreže.

• Title: The geodetic monitoring stability of the dam Drtijščica at Gradiško jezero : master thesis no.: 116/II. GIG

Abstract

In this master thesis we compared two term measurements of the dam at Gradiško jezero. The first term measurement was made in april 2018. The second measurement was made in the end of february 2020. The purpose of master thesis is to find out supposedly unsteady points of network. We adjusted free networks of years 2018 and 2020. We defined the suitable geodetic datum of network with Stransformation. We fastened both networks of years 2018 and 2020 on reference points in new geodetic datum. We adjusted fastened networks. Based on adjusted coordinates of points of both fastened networks we defined potential statistically characteristic shifts of points in network.
