20.500.12556/RUL-32593 Projektiranje in obdelava geodetske mreže za ugotavljanje morebitnih premikov MHE Melje diplomska naloga Designing and processing of geodetic network for detecting of possible movements at the Melje Small HPP Za zagotovitev biološkega minimuma so na Dravi ob jezu Melje postavili Malo hidroelektrarno (MHE) Melje. S tem so porušili ravnovesje v prelivnem zidu kanala, ki je bil zgrajen do HE Zlatoličje. Za ugotavljanje stabilnosti zidu so ob MHE Melje vgradili geotehnično sidro za merjenje sile. Ker je sila v tem sidru narasla preko pričakovane vrednosti, je investitor želel preveriti stabilnost prelivnega zidu z geodetskimi meritvami. Tako smo morali vzpostaviti geodetsko mrežo, ki bi odkrila morebitne premike točk, vgrajenih v prelivni zid. S pomočjo simulacij smo določili optimalno geometrijo geodetske mreže. Izbrali smo primeren instrumentarij in pribor, ki zagotavlja projektirano natančnost meritev. Geodetsko mrežo smo tudi dvakrat izmerili in meritve izravnali. V nalogi smo podrobno opisali teorijo, ki obsega vse geodetske pa tudi ne geodetske postopke in izračune. Na koncu smo izračunali položajne in višinske premike kontrolnih točk, ki smo jih statistično ovrednotili. Na podlagi opravljenih analiz smo poskušali rezultate strniti v nekaj priporočil za investitorja. The Melje Small Hydro Power Plant (HPP) was built at the Melje dam on the Drava River to exploit the biological minimum. This resulted in change of balance at the spilling wall of the Zlatoličje HPP supply channel. To determine stability in the wall, a ground anchor was built. The ground anchor force was greater than expected, thus the investor tried to check the stability of the spilling wall with the help of geodetic measurements. Our task was to develop a geodetic network, which would detect any possible displacements of points built in the spilling wall. We determined the optimal geometry of the geodetic network by using simulations. All the instruments and the geodesy equipment were selected to ensure accuracy of measurement. Geodetic network was measured twice and afterwards the least square adjustments were calculated. The thesis explains into detail the theory, which includes geodetic as well as non-geodetic procedures, as well as the calculations. At the end, we calculated horizontal and vertical displacements of network points and used statistical analysis to evaluate these displacements. On the basis of the analysis we tried to sum up the results and offer the investor a few recommendations. geodezija diplomska dela UNI MHE Melje vzpostavitev geodetske mreže simulacije izmera mreže geodetski datum izravnava meritev premiki graduation thesis geodesy The Melje Small HPP establishment of a geodetic network simulations network surveying geodetic datum network adjustments displacements true false false [M.
