.... To this aim, a selected sector from a cretaceous sedimentary rock cut slope placed in Alicante (Spain) is analyzed using both photogrammetric and terrestrial laser scanner (TLS) point clouds. Using ground control points extracted from printed targets scanned by means of TLS provided very accurate coordinates...

... Abstract In this study, pore structures and water permeation property of a shale rock are analyzed by means of X-ray CT. The target samples are produced Kushiro district in Hokkaido, Japan. Underground of this area is consisted by Cretaceous formation. Firstly, one dimensional permeation tests...

... hydrogeological and seismic conditions expectable in the area. Introduction 1.1 Motivation Tailings, waste products of the ore-dressing processes, are usually stored in a slurry form and pumped to a sedimentation pond which is closed by means of an artificial dam (Ozcan et al., 2013). The database...

... Abstract The punching test can be used to draw mechanical parameters from small pieces of rocks when it is not possible to get samples big enough to perform classical tests. Small rock samples are hold by means of resins which give a certain confinement. Depending on the size of the rock piece...

... vibrations are dynamic phenomena that must be adequately understood and quantified by means of appropriate scientific concepts, followed by specialized engineering applications. This knowledge should be dominated by operators and local authorities in order to specify the acceptability of plant or equipment...

... The paper aims to present a case of an open pit marble and underground quarry. The rock mass characterization has been based on laboratory mechanical tests on marble, geostructural exploration of joint sets, and in situ testing of rock stress by means of hydro fracturing tests. Numerical models...

... ABSTRACT: The cavern housing the machine hall of the S. Giacomo al Vomano power plant was excavated at a depth of 650m in a strongly fractured limestone formation. After extensive in situ exploration, structural analyses by means of numerical models were carried out in the design stage aiming...
