Engineering geological mapping of rock mass on the Špičunak slope (Gorski kotar) using remote sensing techniques : master's thesis

U ovom diplomskom radu prikazana je metodologija inženjerskogeološkog kartiranja stijenske mase na zasjeku Špičunak primjenom daljinskih metoda istraživanja. Inženjerskogeološko kartiranje provedeno je na digitalnom 3D modelu stijenske mase dobivenim primjenom terestričkog laserskog skeniranja (TLS). Kartiranje je uključivalo primjenu manualne i polu-automatske metode prikupljanja podataka o orijentaciji, razmaku i postojanosti diskontinuiteta. Manualna identifikacija navedenih značajki diskontinuiteta provedena je u softveru CloudCompare dok je polu-automatska identifikacija provedena u softveru Discontinuity Set Extractor (DSE). Na temelju provedenih analiza i prikupljenih podataka utvrđene su razlike u točnosti dviju metoda karitranja te su dobiveni podaci primijenjeni za provedbu kinematičkih analiza stabilnosti i GSI kategorizaciju stijenske mase.This Master thesis presents the methodology of engineering geological mapping of rock mass on the Špičunak slope using remote sensing techniques. Engineering geological mapping was performed on a digital 3D model of rock mass obtained using terrestrial laser scanning (TLS). Mapping involved the application of a manual and semi-automatic mapping method to collect data on orientation, spacing, and discontinuity persistence. Manual identification of these discontinuity features was performed in CloudCompare while semi-automatic identification was performed in Discontinuity Set Extractor (DSE). Based on the performed analyzes and collected data, differences in the accuracy of the two mapping methods were determined and the obtained data were applied for the implementation of graphic stability analyzes and categorization of rock mass using the GSI classification system
