20.500.12556/RUL-110723 Obdelava in interpretacija gravimetričnih meritev nad kraško jamo: primer Županove jame magistrsko delo Processing and interpretation of gravity survey above the carst cave: example of Županova jama master thesis Vse geodetske meritve se izvajajo v Zemljinem težnostnem polju, zato ima gravimetrična izmera velik pomen za geodezijo. Brez gravimetrije ne bi mogli določiti npr. oblike geoida in dimenzij Zemlje. V magistrski nalogi nas je zanimalo, ali lahko z gravimetričnimi meritvami odkrijemo jamo. Za delovišče smo si izbrali Županovo jamo, ki se nahaja v bližini Grosupljega. Naloga je sestavljena iz teoretičnega in praktičnega dela. V teoretičnem delu so predstavljeni težnostno polje, gravitacijska sila, težni pospešek in RTK-metoda (ang. Real Time Kinematic) izmere, opisan je uporabljen instrumentarij. V praktičnem delu naloge je opisan postopek terenske izmere (RTK in relativna gravimetrična metoda izmere). V nadaljevanju je predstavljena obdelava meritev. Za izmerjene točke smo izračunali hod gravimetra, relativni in absolutni težni pospešek, popravke in anomalije. Na podlagi anomalije prostega zraka in Bouguerove anomalije smo izdelali dve karti anomalij – eno na ožjem območju Županove jame, drugo pa na širšem območju okrog jame. Na podlagi grafičnega prikaza anomalij smo prišli do ugotovitve, ali lahko Županovo jamo odkrijemo z gravimetričnimi meritvami. All geodetic surveys are conducted in the Earth's gravity field, hence gravity surveys play a crucial role in geodesy. For example, without gravimetry we would be unable to determine the form of the geoid and the Earth’s dimensions. The aim of the Master’s thesis was to determine whether it was possible to discover a cave with the help of gravity surveys. We conducted the surveys in the territory of Županova jama Cave in the vicinity of Grosuplje. The thesis consists of the theoretical and practical part. The theoretical part introduces the concepts of gravity field, gravity force, gravitational acceleration, and the Real Time Kinematic (RTK) survey method. This part also includes a description of the used instruments. The practical part includes a description of the process of obtaining terrain surveys (the RTK method and relative gravity surveys). In the second part of the thesis, we present the processing of the surveys. We calculated the drift, the relative and absolute gravitational acceleration, corrections, and anomalies for the measured points. Based on the free-air anomaly and the Bouguer anomaly we produced two anomaly maps – one for the immediate surroundings of the Županova jama Cave and one for its wider area. Based on the graphic representation of the anomalies, we concluded that Županova jama Cave can be identified with the help of gravity surveys. gravimetrija relativne gravimetrične meritve RTK-metoda izmere anomalija prostega zraka Bouguerova anomalija Županova jama Scintrex CG-5 gravimetry relative gravity measurements RTK method free-air correction Bouguer correction Županova jama Cave Scintrex CG-5 true true false Š.
