Several underground construction methods are examined with reference to recent European applications. An evaluation of the inherent strengths and weaknesses associated with each method is made. The methods under review include grouting in soil, grouting in rock, ground freezing, cast-insitu walls, prefabricated walls, secant piles, slurry shield tunneling, and the New Austrian Tunneling Method as applied to soft ground conditions. The economics of underground construction are examined. The tunneling costs associated with six European metro systems are summarized. Where appropriate, the construction costs are itemized and the cost structures are viewed in the light of the ground conditions and construction methods used. The operation and organization of several European metro authorities are discussed. Tunneling practice in the United Kingdam is studied and used as a focal point for examining such issues as the apportionment of risk under contract and the resolution of contract disagreements. Comparisons are made between urban tunneling costs for rapid transit in the U.S. and Europe. Recommendations for improving tunneling practice are offered. /Author/
