Abstract (english)
The Špičunak location at the state road D3, near the Lokve settlement in the Gorski kotar region, Croatia, is well – known by numerous traffic interruptions caused by slide and rockfall occurrences. The rockfalls at the Špičunak location are mostly predisposed due to geological setting and heavy jointed rock mass in the road cut of approximately 180.0 m length and 23.0 m height. Structural and kinematic analysis of possible future rockfall were carried out following the modern approaches and recent techniques in rockfall hazard analysis. These approaches include application of remote-sensing techniques enabled to ensure digital terrain models (DTM) from three-dimensional high- resolution point cloud (3D HRPC) of the rock cut surface ; engineering geological mapping using combination of remote-sensing techniques and field mapping. The three-dimensional high-resolution point cloud (3D HRPC) were established based on terrestrial laser scanning (TLS) and photogrammetry survey employing unmanned aerial vehicle (UAV) using Structure form Motion (SfM) technique. Based on established 3D models, the cut was analysed to identify the main characteristics of the rock mass structure as well as to detect and map the discontinuities and discontinuity sets, orientation and dip of discontinuities, spacing of discontinuities, persistence of discontinuities and roughness of discontinues. Traditional geotechnical survey was conducted to determine the characteristics of the main discontinuity sets at the cliff, as well as to carry out a rock mass classification using Rock Mass Rating (RMR) system and Geological Strength Index (GSI). Detailed analyses of field survey and remote sensing data pointed to three different zones, based on their properties and rock block standings according to the general orientation and dip of the cut face. To identify possibility of failures associated with the present joint sets and their orientations, the kinematic analyses of plane, wedge and toppling failure mechanisms were carried out based on joint sets discontinuity features data collected by both traditional geological and geotechnical field survey and remote sensing survey and data analysis. Based on the kinematic analyses results, adequate protection measures to prevent further brock block detachments and rockfalls were selected and designed. In this paper we will describe field investigation, establishing of the rock cut model based on remote sensing and traditional geotechnical investigations, stability analysis, as well as design element necessary for ensuring of stability of the rock mass in the cut and safety of the traffic along the road.
