dc.description.abstractRock falls and landslides along major roads cause significant damage to infrastructure in the Gold Coast area, Australia. Current methods of hazard assessment, which mostly include field mapping and data collection for site characterization, are inherently labor intensive and subject to bias due to safety issues and time constrains. However, many of these problems have recently been addressed through the development and deployment of digital imaging technology based on photogrammetry. This method involves the use of high-resolution digital stereo-photographs, from which a three-dimensional image of the slope can be constructed. Such images can highlight the surface texture of slopes and identify potentially unstable zones, thus providing engineers with valuable information regarding the slope design. Photogrammetry is still a relatively new remote sensing technique in Australia and has mostly been used in the mining industry. Little has been done to study the feasibility of its application in civil engineering to solve geotechnical problems related to the stability of natural slopes and road cuts. This paper presents the results of a pilot study aimed at assessing the stability of rock slopes in the Gold Coast area. Field surveys including photogrammetry were performed to study the geological settings of the sites, and characterize the slope's topography and type of discontinuities. Based on the 3-D models, the potentially unstable zones were identified, and slope stability analysis of those areas was performed. The obtained results indicated that photogrammetry can be a helpful tool in assessing geohazard related to slope stability problems.
