Abstract
V diplomskem delu je predstavljena gravimetrija, ki ima kot veda o izmeri in analizi težnosti oziroma izmeri in analizi jakosti težnega pospeška pomembno vlogo pri definiranju vertikalne sestave prostorskega koordinatnega sistema. V prvem delu diplomskega dela so predstavljene vrste meritev v gravimetriji in njihovo izvajanje z vključenimi popravki, ki so potrebni zaradi odstopanj pri meritvah zaradi različnih podzemnih mas ter nekaj malega o sami zgodovini gravimetrične izmere z nekaj primeri. V drugem delu diplomskega dela je predstavljen instrumentarij za merjenje težnega pospeška skupaj z metodami merjenj. Opisana je interpretacija gravimetričnih meritev Bouguerjevih in rezidualnih anomalij, ki so predstavljene s pravilnimi geometrijskimi telesi s poudarkom na gravitacijski privlačnosti vertikalnega valja, ki je v nadaljevanju potreben za izračun anomalije predstavljene v zadnjem, glavnem delu diplomskega dela. V glavnem delu, ki je predstavljen s prilogami na koncu tega diplomskega dela, sem s pomočjo Microsoftovega programa Excel, interpretiral geometrijsko nepravilno simetrično anomalno telo s pokončnimi valji različnih polmerov in enakih višin. Vsak ta valj predstavlja vpliv na površino, vsota vseh valjev pa predstavlja približek skupnega vpliva na površino.

Title:The calculation of Bouguer anomalies, using analytical modelling with elements of cylindrical shapes
Abstract:
The thesis discusses gravimetry – a scientific method of measuring and analyzing gravity or measuring and analyzing the strength of gravitational acceleration – which plays an important role in defining the vertical composition of the spatial coordinate system. In the first part of the thesis we discuss the types of gravimetric measurements and their implementation with included corrections, which are necessary due to deviations in measurements caused by different underground masses. We also shortly discuss the history of gravimetric measurement with some examples. In the second part of the thesis the instruments and methods for measuring gravity acceleration are reviewed. We also examine the gravimetric interpretation of Bouguer's and residual anomalies. These are presented on basic geometric solids, with an emphasis on the gravitational attraction of the vertical cylinder, and then used to calculate the anomaly presented in the last, main part of the thesis. Appendices at the end of the thesis represent its main part. Using Microsoft Excel program, I interpreted a geometrically irregular symmetric anomalous solid with vertical cylinders of different radii and equal heights. Each of these cylinders represents the impact on the surface, and the sum of all the cylinders represents an approximation of the total impact on the surface.

Keywords:gravimetry, gravimetric measurement, gravitational acceleration, corrections, interpretation, anomaly, cylinder
