Abstract

Convertir un tunnel de métro en source d'énergie géothermique, c'est la solution imaginée par des chercheurs de l'Ecole polytechnique fédérale de Lausanne (EPFL). Ils sont parvenus à quantifier les échanges de chaleur dans un tunnel et ont estimé l'économie d'énergie que ferait la ville de Lausanne en utilisant ce système sur la future ligne de métro M3. Les explications de Margaux Peltier, assistante scientifique au Laboratoire de mécaniques des sols de l'EPFL, interrogée par Adrien Zerbini.

Tunnel

A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the 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. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel.

Holland Tunnel

The Holland Tunnel is a vehicular tunnel under the Hudson River that connects Hudson Square and Lower Manhattan in New York City in the east to Jersey City, New Jersey in the west. The tunnel is operated by the Port Authority of New York and New Jersey and carries Interstate 78. The New Jersey side of the tunnel is the eastern terminus of NJ Route 139. The Holland Tunnel is one of three vehicular crossings between Manhattan and New Jersey; the two others are the Lincoln Tunnel and George Washington Bridge.

Tunnel warfare

Tunnel warfare involves war being conducted in tunnels and other underground cavities. It often includes the construction of underground facilities (mining or undermining) in order to attack or defend, and the use of existing natural caves and artificial underground facilities for military purposes. Tunnels can be used to undermine fortifications and slip into enemy territory for a surprise attack, while it can strengthen a defense by creating the possibility of ambush, counterattack and the ability to transfer troops from one portion of the battleground to another unseen and protected.
