Determination of vertical displacements of benchmarks on the area of Ljubljanamarsh |
Sekundarni povzetek: |
Graduate thesis deals with determination of vertical displacements of benchmarks in levelling network on the area of Ljubljana marsh. An overview of old measurments on the area of Ljubljana marsh is given. Levelling method, precision levels and levelling equipment are described. Procedure and results of adjustment of levelling network with software VimWin is presented.
New levelling loops are formed based on data of old measurements and a geological map, so that these take place mostly after solid ground of Ljubljana marsh. Method of determination of vertical displacements is described and accuracy of determination of vertical displacements between two term measurements is given. Unstable vertical points are determined with software Premik. Determination proceedings of vertical displacements of benchmarks for term measurments before year 1992. are also presented. Results are determined unstable vertical points between individual term measurments (comparison of measurments in year 1992, 1994, 1996 and 2000). These results introduce base for further geological interpretation of geodinamical activity. Finally, based on the results, unstable benchmarks are showed on geological map. |

Diplomska naloga obravnava določitev vertikalnih premikov reperjev v nivelmanski mreži, ki je stabilizirana na območju Ljubljanskega barja. Podan je pregled starih izmer nivelmanske mreže na Ljubljanskem barju in opis metode izmere, uporabljenega instrumetarija ter merske opreme. Predstavljen je postopek in rezultati izravnave nivelmanskih mrež s programom VimWin.
Na podlagi podatkov starih izmer ter geološke karte so bile oblikovane nove nivelmanske zanke, tako da te potekajo večinoma po trdinskem delu Ljubljanskega barja. Opisana je metoda določitve vertikalnih premikov ter podana je natančnost določitve vertikalnih premikov reperjev med dvema terminskima izmerama. Predstavljen je postopek določitve nestabilnih reperjev s programom Premik ter postopek določitve vertikalnih premikov reperjev za nivelmanske izmere pred letom 1992. Rezultat so določeni nestabilni reperji med posameznima terminskima izmerama (primerjava izmer iz leta 1992, 1994, 1996 in 2000), ki predstavljajo osnovo za nadaljnjo geološko interpretacijo geodinamičnega dogajanja. Na koncu so na geološki karti na podlagi rezultatov prikazani nestabilni reperji. |
