"Urbanisme souterrain : étude comparée exploratoire"

Responsable scientifique : Sabine Barles
pour le compte de l'APUR et dans le cadre des réflexions conduites sur le réaménagement des Halles à Paris (2005)

L'objectif de ce travail est d'observer l'utilisation du sous sol dans les centres urbains, en particulier le cas parisien à la lumière de quelques expériences significatives. Ont été abordées, dans les cas particuliers de Montréal et de Tokyo, les questions suivantes : facteurs du développement : quelles sont les principales causes du recours au sous-sol statut du sous-sol et place du sous-sol dans l'urbanisme et l'aménagement, typologie des équipements souterrains, usages, perception et évaluation. Le travail est basé sur des travaux antérieurs de l'auteur, complétés par une recherche bibliographique dans la littérature scientifique, le dépouillement de la revue Tunneling and Underground Space Technology et des actes des conférences internationales Espace et urbanisme souterrains, ainsi que sur un contact avec les institutions locales (Urban underground Space Centre of Japan, Observatoire de la Ville intérieure de Montréal...)

Berliner Unterwelten e.V. (Berlin Underworlds' Association)

In the autumn of 1997, a few enthusiasts got together in order to explore this subterranean world. The organization they founded, the “Berlin Underworlds' Association”, locates and documents such hidden installations, making some of them accessible to the public. Furthermore, it uses these sites for cultural purposes (such as exhibitions, theatre performances and concerts). The organization has already discovered numerous forgotten subterranean structures – but many other secrets are still to be discovered down there.
