Marco Barla graduated as a civil engineer in 1996 and has pursued the PhD in geotechnical engineering in 1999 at the Politecnico di Torino, disserting a thesis on Tunnels in swelling ground - Simulation of 3D stress paths by triaxial laboratory testing, the principal adviser being Prof. Michele Jamiolkowski. At that time he was appointed to be the Italian delegate at the YGEC99 (Young Geotechnical Engineers Conference) held in Santorini, Greece 23-25 September 1999. After completing the PhD he was involved in the research activities at the Politecnico, serving as a Research Assistant first, then from 2003, he became Research Associate teaching Rock Mechanics to undergraduates of the I and II Faculty of Engineering. Today he teaches Numerical modelling in geotechnical engineering for Ms students of the Civil Engineering degree and Rock Mechanics for the Master in Petroleum Engineering.
From 2006 to 2012 he was the Vice Director of the DIPLAB Geomeccanica Laboratory of the Department and from 2010 to 2013 he was the commissioner for professional practice examination in Geotechnical Engineering in Torino.
He has been investigating the swelling behaviour of stiff clays with reference to tunnel excavation in the framework of tunnelling in difficult conditions, both from the experimental and theoretical point of view. This work brought to the development of a new triaxial testing procedure and a prediction method for designing tunnels in swelling ground. Recently he has studied the effects of clay swelling on pipe jacking. This was done in 2002, during a leave at the University of Cambridge (UK), in cooperation with the geotechnical group of Prof. Robert Mair.
Research interests also involve the use of discontinuum numerical methods applied to geotechnical problems such as slope stabilities and tunnel excavations. The particle element method was used with success to predict the mechanical behaviour of partially cemented ground (e.g. Turin subsoil) both with reference to the stress strain behaviour of the Turin Metro shallow tunnels and to the applicability of trenchless technologies. In this framework, a new method was introduced, to be used at the design analysis stage to predict the jacking force necessary to install pipelines into the ground by microtunnelling as a function of the degree of cementation of the ground. Recent interests are on the use of radar interferometry for landslides monitoring with reference to deep seated gravitational movements. A new EWS software has been developed to be used together with GBInSAR data for early warning of rock landslides. The rock mechanics aspects related to the development of geothermal energy as a renewable resource and on the use of the combined finite/discrete numerical method for slope stability analyses are current research interests. The geothermal use of urban tunnels is being investigated and relevant outcomes for practical application are obtained.
He is responsible for research projects, contracts and consultancies at the Department and participated to a number of National Research projects (1997, 1999, 2001, 2006, 2009). He is author of a text book, of more than a hundred of scientific papers on international and national journals, on conference proceedings, as well as editor of conference proceedings. He regularly takes part to national and international conferences, also as an invited speaker or member of the Scientific Committee.
From 2001 to 2007 he served as Assistant Editor of the Rock Mechanics and Rock Engineering journal. He acts as a Referee for the ASCE Journal of Geotechnical and Geoenvironmental Engineering, for Rock Mechanics & Rock Engineering, for the ASCE International Journal of Geomechanics and for Tunnelling and Underground Space Technology.
He has been chair of national and international conferences, among with the 11th International Conference of Iacmag and the MIR conferences series in Torino.
He is a member of AGI, Associazione Geotecnica Italiana, of the ISSMGE, International Society for Soil Mechanics and Geotechnical Engineering, of IACMAG, International Association for Computer Methods and Advances in Geomechanics and of EGS-A, Enhanced Geothermal System Association. From 2001 he is a member of the ISSMGE Technical Commitee 209 (Underground construction in soft ground), from 2006 of the Iacmag Committee on Enhancing Membership and in 2009 entered Iacmag Board.
In 2005 he was bestowed of the Iacmag Award for the successful organisation of the 11th International Conference of Iacmag, in 2007 won the Best Paper Award in the topic "The path from characterization to modelling (T2)" at the 11th ISRM Congress with the paper "Setting up a new direct shear testing apparatus" and in 2011 won the IACMAG Excellent Contributions Award.
Besides his research activity he also worked as a consultant for Geodes S.r.l. and Desa S.r.l. in Torino, and received assignments as an expert by the Turin Public Prosecutor's Office. Main professional projects were related to slope stability, tunnelling, sewage systems, foundations, monitoring of geotechnical structures and ground investigation. In 2013 he has founded Resolving s.r.l., a Politecnico di Torino spin-off company which provide services in the field of tunnelling in difficult conditions and early warning monitoring of landslides.
