SOME DESIGN CONSIDERATIONS IN THE SELECTION OF UNDERGROUND SUPPORT SYSTEMS

Guidelines for the design of supports for underground openings in both soil and rock are presented and discussed for several specific situations. The design and construction of both shafts and tunnels are examined. The problems that may occur because of unusual or variable geologic conditions are outlined and the effects of these geologic anomalies on the construction scheme are indicated. Other situations considered include multiple parallel tunnels and crossed tunnels as well as intersections and enlargements of tunnels. Support systems and construction methods which can be easily modified to adapt to variable conditions and requirements are also discussed. The cost of tunnel support systems is evaluated and compared to the total cost of the tunnel. The cost relationships are illustrated by numerous detailed cost estimates of tunnels in both soil and rock. Finally, the problems of ground movements around soft ground tunnels are discussed and methods for predicting the magnitude of settlement over soft ground tunnels are presented. (Author)
