ITA Activities. This site is the best way to know every thing about the International Tunnelling And Underground Space Association, created in 1974 and which gather at the moment 73 Member Nations.
A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
TAC News : 2017 Tunnelling Association of Canada Award Recipients We are pleased to recognize Boro Lukajic as the 2017 recipient of TAC's Lifetime Achievement Award. In addition to his lifetime of exemplary contributions to tunnelling engineering in Canada, Mr. Lukajic served as TAC President from 1994 to 1998.
RASCOR is a globally operating waterproofing specialist. RASCOR is an international corporate group specializing in the development and manufacture of structural waterproofing systems.
Long term ground movements above a tunnel may continue to increase with time after tunnelling in clayey soils as the tunnelling-induced excess pore water pressures dissipate, whilst the changing earth pressure acting on the tunnel leads to further tunnel deformation during consolidation.

26.10.2018 - 15:00 at: Ruhr University, Bochum The use of underground space is a key factor for sustainable development of both industrial as well as emerging and developing countries.
The use of TBM (tunnel boring machine) gradually increases in worldwide tunneling projects. TBM machine are often applied to more difficult and complex geological conditions in urban area, and many problems and difficulties have been reported due to these geological conditions.
The first successful tunnelling shield was developed by Sir Marc Isambard Brunel to excavate the Thames Tunnel in 1825. However, this was only the invention of the shield concept and did not involve the construction of a complete tunnel boring machine, the digging still having to be accomplished by the then standard excavation methods.
International Conference on Coupled Processes in Fractured Geological Media: Observation, Modeling, and Application
KAMY series of Roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines can be used to excavate subway tunnels, road tunnels, railway tunnels and water tunnels without using explosives.
