APPLICATIONS OF THE FLOATING-TUNNEL TECHNIQUE

LES FRANCHISSEMENTS PAR TUNNELS FLOTTANTS

After examining the different possible options for crossing sea-stretches (bridge, floating bridge, underwater floating tunnel, tunnel laid on the sea floor, tunnel cut beneath the sea floor), the article presents various methods of building underwater tunnels. An appendix to the article examines the calibration of cables necessary for balancing a railway tunnel section in ordinary concrete with a density of 2.4, and that of a tunnel in light concrete with the same characteristics. A list of underwater tunnels, built between 1910 and 1975, is added to the article.
