Analiza vpliva manjkajočih meritev na kakovost izravnane mreže na HE Solkan : diplomska naloga št.: 221/GIG

V diplomski nalogi smo obravnavali geodetsko mrežo HE Solkan. Predstavili smo njeno obliko, signalizacijo in stabilizacijo točk v mreži. Opisali smo uporabljen merski instrumentarij, metodo izmere in postopek obdelave meritev. Predstavili smo kako izpad določenih povezav med točkami vpliva na natančnost izravnanih koordinat. Raziskali smo še kakšen vpliv bi imela dodana povezava med izbranima točkama, kjer smo vrednosti dolžine in smeri simulirali na podlagi izravnanih vrednosti koordinat osnovne mreže. Po pridobljenih rezultatih in opravljeni analizi smo prišli do zaključka, da izpad izbranih povezav med točkami ne povzroči bistvenega vpliva na natančnosti izravnanih koordinat. Z izjemo mreže variante 3, kjer so natančnosti izravnanih koordinat precej slabše v primerjavi z osnovno mrežo.

• Title: Analysis of the missing measurements impact on the quality of the adjusted network at the Solkan hydroelectric power plant : Graduation thesis no.: 221/GIG

Abstract

In the thesis, we examined the geodetic network of HE Solkan. We presented its configuration, signaling, and point stabilization within the network. We described the surveying instruments used, the measurement method and the data processing procedure. We demonstrated how the removal of specific connections between points affects the accuracy of the adjusted coordinates. We further explored the potential impact of adding a connection between selected points, where the length and direction values were simulated based on the adjusted coordinates of the fundamental network. Based on the obtained results and the conducted analysis, we concluded that the removal of selected connections between points does not significantly affect the accuracy of the adjusted coordinates. Except for the variant network 3, where point accuracies are considerably poorer compared to the base network.
