DISCONTINUITY SURFACE ROUGHNESS MEASUREMENT TECHNIQUES AND THE EVALUATION OF DIGITAL PHOTOGRAMMETRIC METHOD

摘要

The development of the knowledge from classical photogrammetry to digital photogrammetry is provided simplicity on the works carried out either on the field or on the laboratory. As a result of this development, the application of the photogrammetry science on the various topics is increased its application to be used much more effectively. Various means of discontinuity surface roughness determination methods have been developed for the isolation of the effects of discontinuity surface roughness on shear strength, dilation and friction properties of surfaces. In this study, measurement techniques used for modelling of the discontinuity surface roughness were defined and compared each other. The application of digital photogrammetry on discontinuity surface is determined and a case study is presented. Moreover, results obtained by the use of available measurement techniques were also discussed.
