PREFABRICATED STRUCTURAL MEMBERS FOR CUT-AND-COVER TUNNELS. VOLUME 1. DESIGN CONCEPTS
This report explores the possibility of improving cut-and-cover tunnel construction in urban areas by the use of prefabricated structural members. Various shapes and materials are examined and methods of incorporating these shapes are described. Types of loadings required and design methods are shown. The study concludes that the use of prefabricated members, particularly precast concrete members, is feasible and offers opportunities for significantly reducing surface disruption time. It shows construction methods for the use of precast wall members placed in fluid (slurry) trenches, and precast, prestressed members. This report is the first of two volumes. Volume 2, FHWA-RD-76-114, 'Three Case Studies,' summarizes designs and cost considerations applicable to three actual tunnel sites.
