Abstract

The survey of the geometrical parameters controlling the orientation and spatial frequency of the joints outcropping on rock walls is the starting procedure to assess the geomechanical behaviour of the rock mass. This is of particular importance in the case of civil and mining engineering applications, when high and steep rock scarps are to be monitored. Within the problem of monitoring geostructural discontinuities on a rock slope by photogrammetric facilities, image processing are becoming more and more important. In particular, Digital Terrain Model procedures implemented on analytical plotters, when enhanced with a certain software, allows the survey of the joint sets which characterize the local rock mass conditions. After a theoretical discussion of the method proposed, the paper reports the results obtained for a real rock slope. The photogrammetric acquired data are compared with direct measurements by using the conventional field survey methods. The good agreement between calculated and measured values shows that photogrammetric techniques are a powerful tool for rock slope characteri- zation and monitoring.
