Choice of TBM type for mountain tunnelling under very poor geological conditions: Hybrid, Slurry, Epb, Dsu,...
Abstract: Rock tunnelling under mountains, high covers and in very poor geological conditions might cause major problems to the advance of a TBM, especially in the most critical conditions. To improve the capability of the TBMs to cope with the adverse conditions typical of these applications, the traditional open gripper TBMs evolved to Double Shield in the seventies and to Double Shield Universal at...

Real-time prediction during TBM advance
Abstract: The Bore Tunnelling Electrical Ahead Monitoring (BEAM) system has been installed in all the 6 TBMs utilized in the excavation of the Gold Line metro of Doha (Qatar). The intent was to get a continuous real-time geological forecast ahead of TBMs, useful to predict the quality of the groundmass and the presence of large quantities of water. The article describes how the system was set up,...

Risk sharing in tbm tunnel projects in complex geologies
Abstract: Many infrastructure projects, especially hydropower-railway and aqueduct projects, foresee the execution of long tunnels crossing complex geological formation under significant cover. These projects are often executed under EPC contract conditions, with all design and construction risks to be borne by the Contractor. Even by implementing a very extended investigation campaign, it is almost...
