Handbook on Tunnels and Underground Works

Emilio Bilotta graduated cum laude as Civil Engineer at the University of Napoli Federico II and he got his PhD degree in Geotechnical Engineering from the University of Roma La Sapienza. He is currently Associate Professor at the Department of Civil, Architectural and Environmental Engineering of the University of Napoli Federico II, where he holds courses of Fundamentals of geotechnical engineering for undergraduates and of Tunnels and underground structures and Underground constructions for postgraduates. His main research interests concern tunnelling in urban areas, tunnels under seismic actions, ground improvement for seismic mitigation.Renato Casale is currently CEO at EnginSoft SpA, based in Trento (Italy), and President of the Editorial Board at SIG (Italian Tunneling Association) of "Handbook on Design and Construction of Tunnels ". Prior to this he was Senior Advisor at SWS Group, based in Trento (Italy), President of the Organizing Committee of WTC 2019 at SIG (Italian Tunneling Association) and Senior Engineer at Rocksoil (worldwide known design company in the underground infrastructures).Claudio Giulio di Prisco, graduated at Politecnico di Milano, he developed his doctoral thesis under the supervision of Prof. Roberto Nova at Politecnico di Torino. He collaborated with Prof. Ioannis Vardoulakis and prof. Elias Aifantis. He is Full Professor of Geotechnics and Slope Stability at Politecnico di Milano since 2005 and from 2015, at the same University, Director of the Master on Tunnel Engineering.Salvatore Miliziano is Professor in Advanced Soil Mechanics, Director of 2nd Level Master in Geotechnical Design and Member of Teaching College of PhD Course in Structural and Geotechnical Engineering of Sapienza, University of Rome. His research activities span from theoretical studies to practical applications. He is author of more than 100 scientific papers published in national and international Journals and conference proceedings. Salvatore is scientific head of several Research Projects at Sapienza University involving, among others, several tunnelling projects worldwide. Daniele Peila graduated cum laude as Mining Engineer in 1987, at Politecnico di Torino where, after a period as field engineer in construction firms, he become before research assistant and then professor. He presently is Full Professor at Politecnico di Torino teaching “Tunnelling” and “Reinforcements of soil and rock”. He is Director of the Post-graduate Master Course on “Tunnelling and Tunnel Boring Machines” and chair of the laboratory “Tunnelling and Underground Space”.Andrea Pigorini is an experienced mining engineer that has been working for more than 30 years in design and construction of important infrastructural project in Italy and abroad, with a specific deep experience in tunneling and underground works. He formerly worked in construction companies and he completed his professional background, working for a leading geotechnical engineering company, where he was in charge as designer and project manager of several road, railway and metro tunneling projects.Enrico Maria Pizzarotti, graduated at Politecnico di Milano in 1983, has over 35 years of experience in planning and consultancy of large underground and geotechnical works, including both conventional and mechanized tunnels, underground caverns and stations, also in urban area, among which is the Brenner Base Tunnel (Italian side). He is Chairman of the BoD, Legal Representative and Technical Director of the engineering company Pro Iter S.r.l. based in Milan and a member of the ExCom and SG of SIG, of which he is the animator of the Working Group 2 – Research.
