Determination of the optimal geodetic datum in a horizontal geodetic network of the Formin hydroelectric power plant |
Sekundarni povzetek: |
In the graduation thesis, micro trigonometric network of the Formin hydroelectric power plant's dam is presented. In accordance with law, control measurements of the network are carried out twice a year since 1978. Precise measurements and data processing as well as the stability of the points which define geodetic datum, are significant for determination of the displacements of the control points. Based on geologic observations on the stability of the concrete pillars, geodetic datum in the network of the Formin Hydroelectric power plant was determined in 2004. The geodetic datum is determined by the reference points O4, O5 and O6. The stability of the points which determine geodetic datum as well as the stability of the other reference points is analysed in the thesis. The analysis is based on the data collected in the measurements carried out from 2008 to 2012. In the thesis, there are different ways of determination of the geodetic datum discussed. According to the numerically calculated and graphically presented relative displacements of the reference points during the term measurements, we estimate that probably the point O6 is unstable. Therefore, the points O4 and O5 are defined for the determination of the optimal geodetic datum. In the period discussed, displacements of the reference and control points in the dam are calculated with the new optimal geodetic datum. The results are evaluated and presented in graphs and tables. |
