Research ArticleOpen accessIn the author namesAutomatic Measurement of Drilling Parameters to Evaluate the Mechanical Properties of SoilsDaniele Pettinau, Pierpaolo Oreste, Marilena Cardu, Davide GuidarelliAny underground work, carried out either to perform excavations, should be based on detailed knowledge of the geological, hydrogeological and geomechanical conditions of the underlying materials. The continuous automatic diagraphy is a test that consists in the continuous surveying of drilling parameters, with total destruction of the core, which can be used, together with geognostic probing surveys and a detailed … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Wear of Tunnel Boring Machine Excavation Tools in RockClaudio Oggeri, Pierpaolo OresteSome of the most important aspects in the study of the fragmentation of rock due to the action of TBM disks concern the abrasiveness of the rock and the wear of the tools. The wear of the disks in fact means that they have to be substituted, with consequent effects on the efficiency of the excavation, on the speed of … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 7,662 accessesView PDFCite
Research ArticleOpen accessIn the author namesStability of Rock Pillars with Singular and Persistent DiscontinuitiesPierpaolo OresteProblem statement: The strength of rock pillars in the presence of single, persistent, natural discontinuities can seriously be compromised and lead the pillar to collapse because of instability along the discontinuity itself. Approach: A specific analysis method for this kind of problem has been set up in this study to evaluate the stability of pillars and to determine the dimension … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 6,755 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Transboundary Movement of Hazardous Waste: A Contribution to Improve the Present Technical-Judicial ModelGiancarlo Carosso, Cesare Luceri, Pierpaolo OresteThe expression &#34the transboundary movement of hazardous waste&#34 refers, from the technical point of view, to a series of phases that begin with the creation of a hazardous waste and includes its identification according to international, regional and national standards, its delivery to specialized companies and its movement from the exporting country to the importing country; these phases end with … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 13 Jul 2012 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe International Multimodal Transport of Hazardous Goods and WasteGiancarlo Carosso, Cesare Luceri, Pierpaolo OresteThe international multimodal transport of hazardous goods and waste is a sector of remarkable economic importance. This transport activity is connected to several productive sectors and it can have considerable repercussions on the environment and health as well as on the safety of the workers and third parties that study in the same field. A certain part of the transport … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 10 Jul 2012 · 7,123 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of the Stability of Underground Rock Pillars through a Probabilistic ApproachMassimo Guarascio, Pierpaolo OresteProblem statement: When the room and pillar mining method is adopted, the dimensioning of the rock pillars is one of the most important aspects that need to be faced from the engineering point of view. The available calculation methods are usually simplified and involve the areas of influence method for the evaluation of the mean axial stress induced in the … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 30 Jun 2012 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the author namesTunnel Static Behavior Assessed by a Probabilistic Approach to the Back-AnalysisClaudio Oggeri, Pierpaolo OresteProblem statement: The steps of the validation procedure of the project of a tunnel are briefly illustrated in this study, starting from the geological and structural surveys on the excavation walls and the measurement of the physical and mechanical parameters during the excavation works. Unfortunately, however, the knowledge of the rock mass, which is fundamental to the project, is usually … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Applied Study on the Debris Recycling in TunnellingPierpaolo Oreste, Marta CastellanoProblem statement: A simple calculation has shown what the impact of muck created during the construction of a hypothetical 50 km long and 100 m2 cross section tunnel could be on the environment: around 8 million cubic meters would have to be discharged as waste material. One solution to such a problem could be to recycle (almost a part) the … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 27 Mar 2012 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the author namesMain Aspects of Tunnel Muck RecyclingRossana Bellopede, Fabrizio Brusco, Pierpaolo Oreste, Maurizio PepinoProblem statement: Italy is one of the first countries in the world as far as the number of tunnels is concerned. Many new tunnels are currently under construction or have been planned (300 km of railway tunnels and 150 km of road tunnels, some more than 500 m long, but also metropolitan tunnels). Tunnels are usually excavated in mountain areas … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 9,342 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Tunnel Boring Machine Advancements in Horizontal and Up-Hill TunnelsStefano Fuoco, Pierpaolo OresteProblem statement: Nowadays high levels of experience have been acquired in the excavation of horizontal tunnels using TBM, especially as far as tunnels with small diameters (about 4 m wide) are concerned. Less experience has been acquired in the excavation of tunnels under difficult alignment conditions, as in the case of steeply inclined excavations (up-hill tunnels). Approach: This study presented … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,851 accessesView PDFCite
