摘要:15.00 Normal 0 21 false false false TR X-NONE X-NONE The discontinuity and roughnessproperties of the rocks can be used to obtain information on surfacecharacterization. In this study, it was investigated whether the discontinuityand roughness properties of the rock structure are related to the temperatureof the surface. Selected object which is located at Istanbul TechnicalUniversity Ayazaga Campus has approximately dimensions of 3 m x 1 m. Thediscontinuity regions on the object and the areas which are rougher than theirsurroundings are clearly identifiable by visual interpretation. 3D model ofrock surface was produced by integrating photographs and 12 control pointswhich were homogeneously distributed on the object in order to reflect thesurface realistically. The temperature of the control points marked on thesurface were measured by using an infrared thermometer with non-contactmeasuring capability. These values were used as the basic data to show thetemperature distribution over the entire surface. Temperature distribution mapwith 6 classes representing the temperature range was produced by using IDWinterpolation method in a commercial GIS software. The temperature distributionmap was overlapped on the 3D object model produced by means of RGB photographsfor comparison with the 3D model produced by the thermal images of the samesurface. The temperature distribution in the discontinuity regions that can beclearly seen as rough was examined and obtained results proved that there is astrong relationship between roughness and temperature of the rock surfaces.
