Abstract

Zadatak diplomskog rada bilo je inženjerskogeološko kartiranje na 3D oblaku točaka stijenskog pokosa na državnoj cesti D8 (dionica Trsteno – Orašac), dobivenim fotogrametrijskom analizom, kao daljinskom metodom istraživanja. U radu je opisana metodologija dobivanja 3D modela oblaka točaka pokosa Structure-from-Motion (SfM) metodom iz 475 fotografija, predobrada 3D modela pokosa kako bi ga pripremili za manualno kartiranje orijentacije diskontinuiteta u open-source programu CloudCompare i određivanje orijentacije diskontinuiteta po inženjerskogeološkim zonama pomoću alata Compass. Dobivene orijentacije diskontinuiteta korištene su kao ulazni parametar za kinematičke analize stabilnosti u programu DIPS čime je određen kinematički indeks hazarda (KHI) za svaki mehanizam sloma po inženjerskogeološkim zonama. Terenskim kartiranjem i kartiranjem na 3D oblaku točaka određivani su podaci o ocjeni strukture stijenske mase (SR) i ocjeni uvjeta površine diskontinuiteta (SCR) na temelju kojih je provedena GSI klasifikacija stijenske mase pokosa.

Abstract (english)

The task of the master's thesis was engineering geological mapping on a 3D point cloud of a rock slope along the state road D8 (section Trsteno – Orašac), obtained through photogrammetric analysis as a remote sensing method. The model was created using photogrammetry as a remote sensing method. The methodology includes the acquisition of a 3D point cloud model of the slope using the Structure-from-Motion (SfM) method from 475 photographs. The pre-processing of the 3D slope model is described to prepare it for manual mapping of discontinuity orientations in the open-source software CloudCompare. The determination of discontinuity orientations in engineering geological zones is performed using the Compass tool. These obtained orientations are then used as input parameters for kinematic stability analyses in the DIPS software, resulting in the determination of the Kinematic Hazard Index (KHI) for each failure mechanism in different engineering geological zones. Field mapping and mapping on a 3D point cloud were used to gather data on the assessment of rock mass structure rating (SR) and the evaluation of surface discontinuity conditions rating (SCR). Based on these data, a GSI classification of the rock mass slope is carried out.
