794090 FAULTS IN SWEDISH AND AMERICAN TUNNEL PRACTICE: A FABLE Kuesel, T R Civ Engng, NY, V~9, NI, Jan 1979, P74-77 Swedish and American practices in dealing with unanticipated geological conditions encountered during tur~el construction are contrasted. Swedish practice, illustrated with an example, is directed towards the resolution of the problem with m i n ~ delay and cost. American practice is claimed to lead to excessive delays and costs.

Describes suitable ground conditions for slurry mole tummelling, the soil penetration characteristics of the slurry, observations of surface settl~nent, and su~marises driving experience with the Takken slurry mole at 3 sites in Japan. The percolation limit a~d viscosity coefficient are found to be useful indices for defining the characteristics of specific slurry ~L~es. Avail: Dipl Ing W M Braun, 8 Rowan Road, London W6 7DU, OK
