... and block size) to describe a rock face. But the traditional geotechnical data acquisition is limited in accessibility, geological or geotechnical knowledge, time and scale. The results are often subjective rather than objective and therefore not reproducible (Gaich et al. 2006, Kemeny & Post 2003...

... be smaller than the In-Situ Block Size. In practice, the IBS is estimated based on mean discontinuity orientation and spacing values derived from scanlines recorded manually. Instead, we propose a novel approach: the voxel method. The voxel approach uses all discontinuities visible in the rock face...

... in the UK, most of which were constructed between about 1840 and 1880 and are now around 150 years old (Perry, Pedley & Brady 2003). The distance between the railway lines and the rock face in many of these cuttings is 2.0 m or closer. This is generally less than would be recommended by today s standards...

... A recent development in the use of lidar remote sensing techniques is ground-based laser scanning. Laser scanning of rock faces yields the spatial relation between all scanned rock surface points, at a very high resolution, basically a dense "point cloud" in three-dimensional space. The subject...

... ABSTRACT: The reliability of rock mass geometry characterisation is dependent on the quality and quantity of discontinuity measurement. Time constraints especially at a working rock face and size of the sampling window severely limit the amount of data which can be collected. This paper...
