The application of new slope survey technologies in geotechnics

Abstract

This paper presents two examples of advanced methods of slope imaging on the main road M-22 near the town of Ljig. The slope survey mapping for the research, design and mitigation purposes is still being done using traditional methods. With recent improvement of digital technology manual measurements can be partly eliminated. The application of 3D laser scanning and photogrammetric survey allows to discretize the slope with a large number of points, based on which a detailed 3D surface of the slope could be derived; hence, the interpretation of the details could be significantly improved. Brief description of the study and used methods. Brief description of the study and used methods.
