Abstract: Normally, geological surveys at an
outcrop are conducted by measuring fracture orientation and describe the other
geological information are recorded in a book. Therefore, the reference as well
as the analysis of them is sometimes inconvenient, especially for high slope
and angle, the use of this way is also difficult. The analyzing digital photo
is developed through the application of photogrammetry and other modules, formed a system for collecting,
analyzing and processing data, overcome the difficulties as mentioned above. Specifically,
the fracture orientations are directly determined on the digital photo using
the photogrammetry method and stored in a database. Then, these data can use
for plotting on the graph to analyse the fracture distribution and slope
failure… on each slope surface. In addition, the application also allows the
creation of slope surface in three dimension space (3D) and their vertical
sections. The application of this system has been used in many research
projects, assessing the slope stability and in the tunnel in South Korea from
2005 to present.
Keywords: Slope surface, fracture orientation, left photo,
right photo, photogrammetry method.
